The U.S. House of Representatives Select Committee investigating the deadly Jan. 6 riot at the Capitol has subpoenaed four former members of Donald Trump's administration, including Mark Meadows and Steve Bannon, the panel's chairman said Thursday.

Former White House Deputy Chief of Staff Dan Scavino and former Defense Department official Kash Patel were also subpoenaed and instructed to produce materials and appear for depositions, committee Chairman Bennie Thompson said in a statement.

Meadows, a former congressman, served as Trump's White House chief of staff. Bannon was a White House adviser to Trump.
