Colorado State Rep. Sonya Jaquez-Lewis said she regrets saying Sen. Bernie Sanders had a stroke.

DENVER — Colorado State Rep. Sonya Jaquez-Lewis (D-Longmont) expressed her regret Thursday for a tweet about presidential candidate Sen. Bernie Sanders (D-Vermont).

“So, I am not an MD but I have worked with stroke victims for many years, Bernie has had a stroke or something. Look at the left side of his face. Hope he is okay,” she tweeted during the Democratic primary debate in Las Vegas on Wednesday.

She included a screengrab image of Sanders grimacing during the debate along with the hashtags "Bernies Medical Records" and "Bernie Health."

The tweet has since been deleted. Several Twitter users criticized the post before it was removed.

“I was watching the debate yesterday with some friends and I regret tweeting something about Senator Sanders’ health and medical condition. I deleted the tweet,” Jaquez-Lewis, a pharmacist, told 9NEWS.

“I'm tired of the bullying and harassment of women by Bernie Bros, but I did take it down and regret it.”

Sanders was one of six Democrats who debated on Wednesday night, just days after he made a campaign stop in Colorado. He hosted a rally at the Colorado Convention Center in Denver on Sunday.

Sanders is one of several presidential candidates in Colorado this week ahead of the presidential primary on March 3, Super Tuesday.
