Joe Walsh ends GOP primary challenge to Trump

Former U.S. Rep. Joe Walsh (R-Ill.) has ended his primary campaign against President Trump for the Republican Party's 2020 presidential nomination, after receiving just one percent of the vote in the Iowa caucuses.

Walsh announced the end of his longshot campaign on CNN's "New Day."

"I am ending my candidacy for president of the United States," he told CNN's John Berman. "I got into this because I thought it was really important that there was a Republican — a Republican — out there every day calling out this president for how unfit he is."
