A government watchdog will examine the taxpayer-funded travel costs when President Donald Trump travels to the Mar-a-Lago resort in Florida and the security procedures surrounding those trips, several congressional Democrats announced Tuesday.

The lawmakers requested the inquiry by the Government Accountability Office after reports that Trump, accompanied by Japanese Prime Minister Shinzo Abe, openly discussed North Korea’s launch of a ballistic missile while at the resort. They also raised concerns about the cost to taxpayers.

In a March 24 letter to the lawmakers, GAO said it will examine how the president’s communications and classified information are secured when he’s traveling, including whether a secure space exists at Mar-a-Lago.
