Rep. Ted Lieu Ted W. LieuThe spin on Woodward's tapes reveals the hypocrisy of Democrats Larry Kudlow defends response to coronavirus: Trump 'led wisely' Lieu on Trump 'playing it down' on coronavirus: 'This is reckless homicide' MORE (D-Calif.) and former GOP vice presidential nominee Sarah Palin are attempting to shame each other on Twitter over Lieu's response to the deadly mass shooting in Sutherland Springs, Texas, on Sunday.

Palin, a longtime critic of restrictions on guns, called Lieu a "disgrace" and said Tuesday he should be "ashamed of himself" for walking out of a moment of silence for the victims during Monday's House session.

What a disgrace.



This Rep. should be ashamed of himself. You're a member of Congress, for crying out loud. https://t.co/1NMTFo1Bc4 — Sarah Palin (@SarahPalinUSA) November 7, 2017

“I can’t do this again; I’ve been to too many moments of silences,” Lieu said in a video he posted on Facebook after the walkout. “In just my short period in Congress, three of the worst mass shootings in U.S. history have occurred. I will not be silent.”

Lieu hit back at Palin, calling her out for resigning as Alaska's governor in 2009.

Dear @SarahPalinUSA: Feel free to call me names because I'm cool like that. But I will keep fighting for gun safety. Unlike you I don't quit https://t.co/aUral2ohJz — Ted Lieu (@tedlieu) November 7, 2017

Lieu followed up on the video with a tweet extending his condolences to the 26 victims of the Texas shooting, slamming the National Rifle Association and calling on Democrats to win back the House of Representatives, which could potentially ease the passage of new gun legislation.

My thoughts and prayers are with the victims and families affected by the mass shooting in Sutherland Springs. — Ted Lieu (@tedlieu) November 5, 2017
