“Chris Christie and Marco Rubio can lob accusations of who works less all they want,” he tweeted Wednesday.

“They should both try showing up for work,” Paul added. "Show up or resign/give back your pay."

Paul said Christie's attacks on Rubio for missing Senate votes were hypocritical.

“Chris Christie signed law requiring N.J. public employee to be residents and spend majority of time there,” he wrote on Twitter. "He should follow it or resign.

“Chris Christie has spent 219 days outside of N.J. yet runs on being governor,” Paul continued. "He may not even be a resident, never mind Gov."

Christie hammered Rubio Tuesday for missing a Dec. 18 Senate vote on the $1.8 trillion spending and tax package.

Rubio said he opposed the bill and even threatened to block it but ultimately did not vote.

“Only in Washington could you have the guts to say I’m against something that you have a vote to vote no on and then just not go and then put out a press release after it gets passed to say, ‘This is why I was opposed to it,’” Christie said at an Iowa town hall.

“Well, dude, show up to work and vote no, right? Just show up to work and vote no, and if you don’t want to, then quit.”

Former Gov. Jeb Bush (R-Fla.) has also criticized Rubio’s absences from Congress.

A super-PAC aligned with Bush released an ad Tuesday lambasting the senator for missing a top-secret intelligence briefing after the Paris attack.

Rubio's campaign has dismissed those attacks, noting that Rubio attended other hearings on Paris.

According to data released by C-SPAN this week, Rubio has the Senate’s worst attendance record for 2015. He missed 35 percent — or 120 of the 339 roll votes — last year.
