Joe Walsh, a conservative former U.S. congressman turned talk show host, on Sunday became the second Republican to challenge President Donald Trump for the party's 2020 White House nomination.
Walsh, 57, announced his long-shot bid to unseat Trump, who has strong support among Republicans, after sharply criticizing the Republican president as a liar and a bully who is unfit for office.
"I'm running because he's unfit," Walsh told ABC's "This Week" program. "Somebody needs to step up."
“I think Walsh’s plan to attack Trump for his dishonesty, amorality, instability and incompetence is absolutely the right approach, and I’ll do whatever I can to help,” Conway told The New York Times in an interview.
