Wisconsin Gov. Scott Walker is endorsing Texas Sen. Ted Cruz in the Republican presidential race.
Walker announced his decision Tuesday on Milwaukee conservative talk radio, saying "it's time we elect a strong new leader. I've chosen to endorse Ted Cruz."
Walker had signaled last week that he was likely to back Cruz, saying then that he was the only candidate who has a chance at beating front-runner Donald Trump. When Walker ended his presidential campaign last year, he called on others to join him in dropping out to make it easier to defeat Trump.
It's unclear how much Walker's backing will help Cruz in the state ahead of its April 5 primary. Walker's approval rating hasn't exceeded 40 percent in over a year.
