WASHINGTON, Oct 13 (AFP) - The U.S. House of Representatives committee probing the Jan. 6, 2021, attack on the U.S. Capitol by Donald Trump's supporters voted unanimously on Thursday to subpoena the former president, a move that could lead to criminal charges if he does not comply.

The House select committee's seven Democratic and two Republican members voted 9-0 in favor of issuing a subpoena for Trump to provide documents and testimony under oath in connection with the storming of the Capitol.

"He must be accountable. He is required to answer for his actions. He is required to answer for those police officers who put their lives and bodies on the line to defend our democracy. He is required to answer to those millions of Americans whose votes he wanted to throw out as part of his scheme to remain in power," the panel's Democratic chairman, Representative Bennie Thompson, said.

The vote came after the committee spent more than two hours making its case - via statements from members, documents, and recorded testimony - that Trump planned to deny his 2020 election defeat in advance, failed to call off the thousands of supporters who stormed the Capitol, and followed through with his false claims that the election was stolen even as close advisers told him he had lost.

Federal law says that failure to comply with a congressional subpoena is a misdemeanor, punishable by one to 12 months imprisonment. If the select committee's subpoena is ignored, the full House must vote on whether to make a referral to the Department of Justice, which has the authority to decide whether to bring charges.
