"The search and review of records confirmed that there is no system for keeping track of presidential visitors at Mar-a-Lago, as there is at the White House Complex," Special Agent Kim Campbell said on Thursday, ABC news reported.
"Specifically, it was determined that there is no grouping, listing or set of records that would reflect presidential visitors to Mar-a-Lago."
A lawsuit was filed earlier this year by three government transparency groups, Citizens for Responsibility and Ethics in Washington (CREW), the National Security Archive and Columbia University's Knight First Amendment Institute, in efforts to make Trump's meeting at his personal residences public information.
"The public deserves to know who is coming to meet with the president and his staff," CREW Executive Noah Bookbinder said when the lawsuit was filed.
"We are glad that as a result of this case, this information will become public for meeting at his personal residences — but it needs to be public for meeting at the White House as well," Bookbinder added.
Although the Secret Service does have presidential schedules that could shed light on who Trump has met with as his resort, the Justice Department believes that the records are not subject to the Freedom of Information Act (FOIA), and thus cannot be released to the public.
"The remaining records that the Secret Service has processed in response to the Mar-a-Lago request contain, reflect, or otherwise relate to the President's schedules," the Justice Department wrote in a letter to the transparency organizations.
