Washington (CNN) President Donald Trump's July Fourth event and protests surrounding it cost the Washington government approximately $1.7 million and drained the city's fund for security, according to Democratic Mayor Muriel Bowser.

The Emergency Planning and Security Fund will be depleted before the end of the 2019 fiscal year and will stand more than $6 million over budget, Bowser said in a letter to the President on Tuesday, citing recent estimates by the District's Homeland Security and Emergency Management Agency.

Bowser requested that the Trump administration commit to fully reimbursing the fund, which provides for public safety at events in DC and response support to terrorist threats or attacks in the district, and accommodates requests from the US Secret Service.

"(W)e 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," Bowser wrote.

The Washington Post first reported Bowser's letter to Trump.
