In a letter to the president Tuesday, D.C. Mayor Muriel E. Bowser (D) warned that the fund has now been depleted and is estimated to be running a $6 million deficit by Sept. 30. The mayor also noted that the account was never reimbursed for $7.3 million in expenses from Trump’s 2017 inauguration.

Bowser requested that the White House commit to fully reimbursing the fund.

“We ask for your help with ensuring the residents of the District of Columbia are not asked to cover millions of dollars of federal expenses and are able to maintain our high standards of protection for federal events,” she wrote.
