A chief architect of Project 2025 is launching a Republican primary challenge to Sen. Lindsey Graham in South Carolina.

The former director of Project 2025, Paul Dans, launched a Senate race against longtime incumbent Sen. Lindsey Graham, R-S.C., on Monday, saying he wants to bring Project 2025’s controversial right-wing agenda to the Senate—and becoming one of several further-right candidates now challenging latter-day Trump ally Graham.

Paul Dans will run in the South Carolina primary highlighting the work of Project 2025, a conservative blueprint that President Trump has employed during his second term.
