Becerra tweeted Wednesday morning that Sanders has been advocating for support of immigrant families recently but called into question his record.

"We've been hearing a lot from @BernieSanders about supporting immigrant families of late. Where was he before he ran for president?" Becerra asked in one tweet.

He called Sanders out for voting against the late Sen. Ted Kennedy's (D-Mass.) comprehensive immigration reform bill in 2007. He also said Sanders voted for a measure designed to protect Minutemen, anti-immigrant militias on the U.S.-Mexico border.

The chairman of the House Democratic Caucus called on Sanders to be honest about his record, saying fixing the country's immigration system is "tough, serious biz" and that "high-flying talk [without] a track record of action deceives those who need us most."

Last weekend, Sanders vowed to use executive action on immigration if he is elected president. He said at a rally in Nevada that if Congress does not address the problem, "We will use the executive powers of the White House."
