Founders, including allies to Rep. Adam Kinzinger (R-Ill.), an outspoken critic of the former president, started the PAC, which is called Americans Keeping Country First. Mario Castillo is one of the group’s advisers. The new PAC is anticipated to support the 10 Republican House members and Sen. Lisa Murkowski (R-Alaska), who will face an election in 2022, in the primaries and general elections.
