The U.S. Secret Service paid at least $63,700 in a series of payments to President Trump's Mar-a-Lago resort in Palm Beach, Fla., according to a new report.

The expenses were designated as hotel costs and documents reveal that the payments, most of which were made between February and April as Trump made frequent visits to the club. The resort attracts members who rake in millions of dollars for the club each year.

The purposes of the expenses are not clear from the redacted documents reviewed by CNN, and it is uncertain if additional payments were made.

It's typical for the Secret Service to pay private businesses for these types of costs associated with protecting the president, but ethically, questions are being raised as to whether Trump's visits are contributing to personal gain.

Although Trump transferred Mar-a-Lago and other holdings into a trust during his time in office, he did not adhere to precedent by divesting them. As a result, he could obtain profits from his businesses upon leaving office.
