Rep. Joe Heck (R-NV) told voters in Nevada Saturday that it is time for Donald Trump to step aside.

Heck, who is campaigning to replace retiring Sen. Harry Reid (D-NV), made the statement at a get out the vote rally in Nevada as he was heckled.

“We deserve a candidate that can ask themselves at the end of the day ‘did I live my life with honor, and do I deserve to be elected President of the United States?'” Heck said during a rally that was aired live on MSNBC. “I believe our only option is to formally ask Mr. Trump to step down.”

Heck had previously endorsed Donald Trump to be the president of the United States. After the 2005 video of Trump’s lewd comments about women sufaced on Friday, Heck admonished Trump’s comments, but he did not immediately pull his support.

Heck now joins Sen. Kelly Ayotte (R-NH), Rep. Jason Chaffetz (R-UT), Rep. Martha Roby (R-AL) in pulling his support of Trump.

Heck’s Democratic opponent Catherine Cortez Masto, Nevada’s former Attorney General, wasn’t going to let Heck off the hook that easily, however.

“For nine months, Joe Heck has been Donald Trump’s strongest supporter in Nevada as Trump has demeaned and disrespected women, made racists comments towards Latinos and showed himself completely unfit to be President. Heck said he had ‘high hopes’ about Trump becoming President, that he completely supported him and that he had no doubts about Trump having his finger on the nuclear button. What you’re seeing now is not leadership, it’s Joe Heck trying to save his career, ” Masto said in a statement emailed by her campaign.
