(CBS NEWS) -- With Eric Trump’s trip to the United Kingdom this week, the international hotel and car rental costs for the Secret Service agents who protect him and his brother Donald Trump Jr. have topped $190,000 since January 1st, according to a review of purchasing orders by CBS News. 

All of those bills are paid by taxpayers.

Documents for Eric Trump’s trip this week to Dublin show that $4,029.85 was spent on limousines for his visit and $11,261 to cover the hotel costs of the Secret Service agents who protect him.

These purchase orders do not include airfare costs for Secret Service agents who traditionally conduct advance trips to the location in preparation for visits by protectees. It also does not include the cost of the salaries paid to the agents who protect members of the president’s family.

The Trump Organization did not respond to a request for comment.

Eric Trump’s trip to the United Kingdom is his fifth international trip since the start of 2017. He went to Uruguay and the Dominican Republic on his own and accompanied his brother Donald Trump Jr. on his trips to Dubai and Vancouver, Canada. 

The trips by the Trump sons are to promote Trump-branded properties in those countries. According to an analysis by the Economist magazine, the Trump Organization’s international deals account for less than 10 percent of the company’s value.
