WASHINGTON, Oct 8 (Reuters) - Former U.S. President Donald Trump's showcase hotel in Washington bled millions of dollars during his time in office even as he concealed payments from foreign governments, a U.S. House of Representatives panel said on Friday.

The House Committee on Oversight and Reform said recently obtained government documents raised "troubling" questions about the Trump International Hotel, a historic building the Trump Organization leases from the federal government and a popular gathering spot for his supporters and for foreign dignitaries.
