Speaker Nancy Pelosi stunned the GOP on Wednesday by vetoing two of House Minority Leader Kevin McCarthy's choices for a select panel investigating the Jan. 6 Capitol attack, a move all but guaranteed to spark a Republican boycott of the probe.

Pelosi rejected Rep. Jim Banks (R-Ind.), who was tapped to serve as ranking member, and Rep. Jim Jordan (R-Ohio), both of whom voted to challenge certification of President Joe Biden’s electoral wins earlier this year. Her decision sent shock waves through the House and is likely to galvanize House Republicans against any participation in the investigation.
