Trump gave his endorsement to Wisconsin Senator Ron Johnson (R-WI), who is rumored to be considering retirement. The former president said that Johnson possesses the “kind of courage we need in the U.S. Senate.” "Even though he has not yet announced that he is running, and I certainly hope he does, I am giving my Complete and Total Endorsement to Senator Ron Johnson of Wisconsin," Trump wrote in a statement. "He is brave, he is bold, he loves our Country, our Military, and our Vets. He will protect our Second Amendment, and everything else we stand for. It is the kind of courage we need in the U.S. Senate. He has no idea how popular he is. Run, Ron, Run!"
