White House press secretary Sarah Sanders slammed Rep. Ted Lieu, D-Calif., over an incorrect tweet he shared about her comments on the Republican tax bill, saying the congressman should “spend less time tweeting, more time doing your job.”

Sanders and Lieu engaged in a back-and-forth on Twitter on Tuesday after the Hill published a now-deleted tweet about comments Sanders made during an interview on Fox News.

The White House press secretary was asked to respond to accusations from some Democrats that the GOP didn't ask for their input when drafting the tax bill.

“This is a president who would’ve been happy to take [Democrats’] call and certainly happy to have their vote, to help Americans have more money in their paychecks, more money in their pockets, more money for businesses to reinvest in this country,” Sanders told Fox News on Tuesday. “That’s something that Democrats shouldn’t need to be begged to be a part of. They should’ve been begging and banging down the door of the building behind me to be part of this process and to be part of helping Americans be more successful.”

Lieu, sharing the tweet from the Hill, accused Sanders of lying.

“Dear @PressSec: You don’t serve in Congress. I do. And I can say with absolute certainty that you are lying,” the California Democrat tweeted.

It’s unclear what the original tweet from the Hill said.

Sanders then accused Lieu of failing to read the article and criticizing her based on the incorrect tweet.

“Dear @tedlieu - I don’t serve in Congress, but I can read. If you had read the story, not an incorrect tweet, you would see that what I said was Dems should be begging to help Americans keep more of their money. You should spend less time tweeting, more time doing your job,” she said.

The GOP-led House passed the Republican tax bill on Tuesday. The Senate is expected to vote on the proposal later in the evening.
