The House select committee investigating last year's Capitol riot voted Thursday to subpoena former U.S. President Donald Trump.
"He is required to answer for his actions," Democratic Congressman Bennie Thompson, chair of the nine-member panel, said in its 10th public hearing Thursday afternoon.
The committee argued the Republican was directly involved in efforts to overturn the results of the 2020 presidential election, in which he lost to Democrat Joe Biden.
Trump blasted the unanimous vote from the panel to subpoena him for documents and testimony.
"Why didn't the Unselect Committee ask me to testify months ago?" he wrote on his Truth Social social media platform, calling it "a total bust."
On Jan. 6, 2021, thousands of individuals -- mostly Trump's supporters -- stormed the Capitol in Washington, D.C., and disrupted a joint session of Congress to affirm the 2020 presidential election results.
Approximately 140 police officers were assaulted. Authorities have linked at least five deaths to the mayhem.
It was the worst attack on the U.S. Congress in more than 200 years and led to Trump's second impeachment by the House of Representatives shortly before his term officially ended.
