Iran says it has sentenced an American graduate student to 10 years in prison for spying for U.S. and British intelligence agencies. The Princeton University student was in Iran doing research when he was arrested.

Xiyue Wang, 37, is pursuing a Ph.D. in Eurasian history, studying local government in predominantly Muslim regions during the late 19th and early 20th centuries. Stephen Kotkin, Wang's advisor at Princeton, says Wang came well-prepared for an extremely ambitious thesis topic.

President Trump has spent much of the past year talking about hackers who stole emails for political reasons.

But at Trump Hotels, hackers of a different sort were attacking.

Starting last summer, hackers broke into the system that manages the reservation booking service for 14 Trump hotels, stretching from Washington, D.C., to Scotland to Canada to Brazil.

The Trump Organization appears to be making only a limited effort to live up to President Trump's promise to give the U.S. Treasury all foreign profits from his hotels and resorts, according to documents released in recent days.

Trump made the promise in mid-January as a way to avoid violating the U.S. Constitution's emoluments clause, which prohibits a president from accepting gifts and payments from foreign governments.

For Sale: Spectacular Caribbean waterfront property in French St. Martin.

Amenities: Swimming pools, tennis court, full staff.

Owner: President of the United States, Donald Trump.

This sale is the first known major divestiture of a Trump property since he became president. Trump bought Le Chateau des Palmiers about four years ago; the asking price at the time was $19.7 million.

For the second time in less than two weeks, the State Department has hit the "delete" button after complaints that it was promoting Trump family business endeavors.

This time, the State Department deleted a retweet of a post by President Trump's daughter, Ivanka Trump.

On Inauguration Day, Donald Trump placed his hand on a Bible and promised to preserve, protect and defend the Constitution. At the time, many ethics experts waited to see if Trump would divest himself of his multi-billion dollar business interests.

"And he didn't do it," says Zephyr Teachout, an associate law professor at Fordham University. "So immediately upon becoming president we filed a lawsuit to get him to stop violating the Constitution."

China's Foreign Ministry is defending a decision to grant Ivanka Trump new trademark rights for her line of handbags, jewelry and spa services. The three new trademarks were approved April 6 while the president's daughter and her husband, Jared Kushner, sat next to Chinese President Xi Jinping and his wife at dinner at President Trump's Mar-a-Lago resort in Florida, according to The Associated Press.

Two plaintiffs involved in the hotel and restaurant industry have joined a lawsuit alleging President Trump is violating the Constitution, potentially bolstering the effort. The lawsuit centers on whether Trump is breaching the Emoluments Clause — a provision in the Constitution that prevents government officials from accepting gifts, benefits and the like from foreign leaders.

As congressional and FBI investigators in Washington explore potential ties between President Trump's 2016 campaign and Russian intelligence services' meddling in the election, they're searching for one particular clue: money.

Loans, payments, sweetheart deals or other transactions are a tried and tested way that Russia's spy agencies get access to or control over people who interest them.

The top Democrat on the House Intelligence Committee, Rep. Adam Schiff, told NPR that evidence of such entanglements are one thing his panel is looking for.

The White House says President Trump has a new special assistant on his staff — his daughter Ivanka. The announcement comes a week after the president's oldest daughter moved into her own office in the West Wing to work on women's issues.

Her shift from an informal adviser at the White House to an unpaid government employee is small but important. She was already applying for security clearance, had access to classified information and was meeting with world leaders.

The Trump International Hotel in Washington, D.C., has generated plenty of controversy since it opened last fall.

But concerns about President Trump's conflicts of interest might not be enough to stop his company from opening a second hotel in the nation's capital.

President Trump got good news on Thursday from the federal agency that oversees the three-year-old lease on his five-star hotel in Washington, D.C.

The General Services Administration said in a letter that the Trump Organization is in "full compliance" with the lease on the luxury hotel that's located just blocks from the White House.

When Donald Trump was elected president, his daughter Ivanka Trump said she would move to Washington, D.C., but not into a White House office.

President Trump's former national security adviser, Michael Flynn, collected more than $50,000 from Russian companies, including a Kremlin-backed television network, according to documents released in a congressional inquiry.

In early January, Eric Trump took a trip to Uruguay to check progress on an unfinished Trump tower. About a month later, he was in the Dominican Republic, seeing whether an earlier resort project could be revived. He joined his brother, Donald Jr., a couple of weeks later at a ribbon-cutting ceremony for a Trump-branded golf course in Dubai. Then the two popped up earlier last week in Vancouver, Canada, for the opening of a new Trump hotel.

For more than a decade, Kuwait's ambassador to the U.S., Salem al-Sabah, has held a gala event every Feb. 25 to celebrate his country's national day. The annual holiday commemorates the tiny Gulf state's independence from British rule in 1961. Traditionally, the event has been held at the Four Seasons Hotel, in the heart of Washington, D.C.

But Sabah says he feels his guests have wanted a change. Last year, he held the celebration at the Newseum. For this year, he and his wife, Rima, looked into the newly opened Trump International Hotel as another possibility.

President Trump has gotten off to a rocky start with one NAFTA partner — Mexico. On Monday, he turns to the other partner, Canada, when he hosts Prime Minister Justin Trudeau at the White House.

Hundreds of billions of dollars of trade pass between Canada and the U.S. each year, $540 billion in 2015 alone. Yet Trump has called NAFTA the worst trade deal ever and is threatening to rip up or at least renegotiate it.

The official address of Toronto's Trump International Hotel and Tower is 325 Bay St., in the middle of the city's financial district. Think of it as Canada's answer to Wall Street. But the hotel's entrance is actually around the corner. So instead of seeing a grand facade bearing the Trump name, what you see from the prestigious Bay Street side is a loading dock.

President Trump has said he won't do any new foreign deals while in the White House, but that won't stop new Trump hotels from springing up across the United States.

President Trump is now filing the documents needed to remove his name as top executive at his companies, finally making good on a promise to leave management by Inauguration Day.

On the day before taking office, President-elect Donald Trump arrived in Washington, D.C., to kick off inaugural festivities.

His first stop: a leadership luncheon at his new five-star hotel, the 263-room Trump International Hotel, blocks from the White House.

The hotel has been the center of a debate over conflicts between Trump's business interests and the presidency.

Incoming White House spokesman Sean Spicer told reporters Thursday Trump's use of the hotel for a reception shouldn't come as a "shocker" to anyone, and he even gave his boss's hotel a plug.

On Friday, when Donald Trump puts his hand on a Bible and takes the oath of office, ethics experts say he may very well be in violation of a lease on one of his premier hotels.

The Trump International Hotel is a grand dame of a building on Pennsylvania Avenue, just a stone's throw from the White House. It has become something of a tourist destination in Washington — and a rallying point for protesters — since Trump won the election. This week, they snarled traffic in front of the hotel, and one demonstrator suffered serious burns after trying to set a fire outside the building.

President-elect Trump told a press conference Wednesday that he would step back from running his company to prevent possible conflicts of interest once he's in office. To help prove it, he said he had just rejected a $2 billion deal to develop a golf course in Dubai, United Arab Emirates, adding that he wasn't required to do so because he isn't bound by any conflict-of-interest laws once he's president.

In late October, just weeks ahead of the election, President-elect Donald Trump made a quick detour to Washington for the official opening of his new five-star hotel, just a few blocks from the White House.

President-elect Donald Trump has promised to step back from his business interests when he takes office. He says he'll let his two adult sons take the helm and that he won't make any new deals while he's president.

While he's unwinding some of his roughly 500 business deals involving about 20 countries as Inauguration Day approaches, many others are moving forward, causing concern about conflicts of interest.
