Reform groups in Mexico have been trying for years to persuade politicians to regularly disclose their assets and income, pointing to their northern neighbor as an example of a place where financial disclosure is the norm in government.

Then came President Trump, who has steadfastly refused to release his tax returns.

Kellyanne Conway, a top adviser to President Trump, may have violated federal ethics rules Thursday when she urged shoppers to buy Ivanka Trump's retail brand, following the decision by several retail companies to drop the line because of poor sales.

"Go buy Ivanka's stuff, is what I was [saying] — I hate shopping and I'm going to go get some myself today," Conway said in an interview on Fox & Friends.

President Trump's approval rating with voters may be the lowest on record for an incoming chief executive. But in one way at least, his popularity is improving a bit.

The value of Trump as a commercial brand, although still very low, has ticked up since August, according to the Reputation Institute, which measures the worth of various business brands.

Donald Trump's presidential campaign had many unusual aspects, not the least of which was the huge amount of money it funneled into Trump's own businesses.

And now there's a new twist: Such payments can continue indefinitely because he's already declared himself a candidate for re-election in 2020.

Leaders in the U.S. technology sector say President Trump's executive order banning immigrants from some Muslim-majority countries will sow confusion in their businesses and undercut the diversity that has been a linchpin of the industry's growth.

The CEOs of Google, Twitter, Facebook and Apple all issued statements condemning the ban and complaining that the order was pushed through so quickly it left great uncertainty about the status of some of their best employees.

President Trump's continued business dealings have generated plenty of teeth-gnashing about whether the occupant of the White House will be profiting off his new role.

The question is who has the "standing" to do anything about it?

A team of ethics experts and legal scholars filed a lawsuit in federal court Monday morning that says President Trump's overseas businesses violate the Constitution's Emoluments Clause, which bars presidents from taking money from foreign governments.

President-elect Donald Trump takes office on Friday having largely failed to address concerns about the many conflicts of interest posed by his business interests.

Although Trump has settled a few of the outstanding legal and regulatory disputes hanging over him, he remains in the unusual position of presiding over countless policy decisions that will affect his own businesses.

These days, plenty of consulting firms make money peddling advice on cybersecurity. Only one is run by a man designated special adviser to the president of the United States.

Earlier this month, President-elect Donald Trump named former New York City Mayor Rudolph Giuliani, who heads a cybersecurity practice at the Miami-based law firm Greenberg-Traurig, as his chief adviser on cybersecurity issues.

President-elect Donald Trump has suggested he may give his daughter and son-in-law some roles in his new administration, but a 1967 anti-nepotism law makes doing so a lot more complicated.

The law bars presidents from hiring relatives to Cabinet or agency jobs, although a federal judge has ruled that it doesn't apply to White House staff jobs.

Some prominent conservatives have signed on to a letter warning President-elect Donald Trump that he needs to sell off his businesses to address his many conflicts of interest.

"Respectfully, you cannot serve the country as president and also own a world-wide business enterprise, without seriously damaging the presidency," says a letter sent Monday by a bipartisan group of politicians, ethics advocates and academics.

President-elect Donald Trump insists he can do all the business deals he wants while serving in the White House, but a 2012 law barring insider trading by government officials could make doing so a lot more complicated.

One day after Vanity Fair printed a highly critical piece about one of his restaurants, President-elect Donald Trump escalated his feud with the magazine's editor, calling him a "no talent."

"Has anyone looked at the really poor numbers of @VanityFair Magazine," Trump said in an early-morning Tweet. "Way down, big trouble, dead! Graydon Carter, no talent, will be out!"

Trump Tower, the building that President-elect Donald Trump calls home, bills itself as "one of the world's elite luxury residences, catering to public figures, athletes, celebrities and other affluent sophisticates."

These days, some other people have taken up residence there as well: Secret Service agents.

Trump has said that his family won't move into the White House right away and will remain, for a few months at least, in the world-famous steel-and-glass office and residential building where they occupy three floors.

President-elect Donald Trump suggested Sunday that he will not sell off his business operations to avoid conflicts of interest during his presidency. He said he will instead allow his grown children to manage them.

"My executives will run it with my children. It's a big company. It's a great company. But I'm going to have nothing to do with management," Trump told Chris Wallace on Fox News Sunday.

Donald Trump was elected president promising to use his business-world experience and negotiating skills to help boost the American economy. Now that he's about to take office, a lot of people hope he'll leave the business world behind.

Two-thirds of those responding to a Bloomberg News poll said they think Trump needs to choose between being president and being a businessman, to avoid the appearance of a conflict of interest.

He was a flamboyant, alpha-male billionaire who said things no career politician ever would — someone who promised to use his business savvy to reform the system and bring back jobs. Voters believed that his great wealth insulated him from corruption, because he couldn't be bought.

But his administration was marked by criminal investigations and crony capitalism.

President-elect Donald Trump has chosen Wilbur Ross Jr., a billionaire investor and turnaround specialist, as his commerce secretary.

Ross announced his selection Wednesday during a joint CNBC interview with longtime Wall Street banker Steve Mnuchin, Trump's pick for Treasury secretary.

"Wilbur Ross is a champion of American manufacturing and knows how to help companies succeed," Trump said in a statement announcing his choice.

The Donald J. Trump Foundation has acknowledged in a tax filing that it violated the ban against "self-dealing," or using its assets to help its leader's business or personal interests, The Washington Post reported.

When comedian Bill Maher offered $5 million to Donald Trump if he could prove he wasn't the son of an orangutan, Trump did something he's done many times before: He sued.
