House Minority Leader Kevin McCarthy is in Poland with lawmakers from both parties to meet foreign leaders about the nearby war in Ukraine, and one member’s participation in the trip is raising eyebrows.

Florida Rep. Stephanie Murphy’s decision to participate in the trip is notable since she is a member of the Democratic-led Jan. 6 select committee. The panel is probing the events of the day when supporters of outgoing President Donald Trump stormed the Capitol in an attempt to overturn his loss to Democratic rival Joe Biden, who won the Electoral College in 2020 and took office two weeks later. House Republicans, led by McCarthy, have strongly criticized the Jan. 6 panel’s work, and the California Republican prevented his own members from participating in it.
