President Trump promised to keep his businesses out of his presidency. But taxpayers are already footing part of the bill for the Trump Organization's business trips.
In January, Eric Trump took a business trip to Uruguay. As the president's son, he gets Secret Service protection.
The Washington Post found it cost nearly $100,000 to provide the Secret Service with the rooms and support they needed to keep him safe.
Eric Trump visited the Trump Tower Punta del Este. The Trumps don't actually own the tower, but they licensed their name to it for between $100,000 and $1 million.
Since President Trump has refused to divest of his companies like past presidents, that means taxpayers just paid for part of a business trip that the president will probably profit from.

Eric founded the Eric Trump Foundation when he was 23-years-old. The charity aims at raising money for children at St. Jude Children’s Research Hospital. The organization's website says they have "donated and pledged nearly $30 million dollars to St. Jude."

Eric runs the Trump Organization's golf courses. Since joining the organization in 2013, Eric increased the number of international golf courses from three to 17.

While speaking on the campaign trail in October, Eric Trump mistakenly introduced then-vice presidential candidate Mike Pence as the Governor of Illinois. Pence is the governor of Indiana. The 32-year-old chalked it up to a slip of the tongue.

Eric made headlines on Election day after he tweeted a photo of his ballot while voting for his dad. The tweet was quickly deleted, but not before garnering over 3,000 retweets and over 8,000 likes.
It is illegal in New York to share a photo of your election ballot.
An ethics expert told the Post, "This is an example of the blurring of the line between the personal interest in the family business and the government."
Don't be surprised if something like this happens again. The Trump Organization has dozens of businesses all over the world. And since the president has refused to release his tax returns, we don't know how many conflicts there are.
