Sen. Marco RubioMarco RubioWill Republicans stand up to the NRA's insurrection rhetoric? The Hill's Whip List: Senate ObamaCare repeal bill Ivanka Trump turns to House GOP on paid family leave MORE (R-Fla.) will meet with Facebook CEO Mark Zuckerberg at the social media company's campus in California on Wednesday, according to reports.

Rubio is on a fundraising swing through the Golden State this week for his political action committee, Reclaim America, and reelection committee.

It is not clear what’s on the agenda for the meeting between the rising GOP star and the Facebook founder, but a source told CNN that “their shared commitment to fixing America’s broken immigration system” is likely to be on the table.

Rubio is a member of the Gang of Eight that helped push reform legislation through the Senate in June. 

Zuckerberg co-founded a political advocacy group,, earlier this year to promote comprehensive immigration reform.

Unlike other members of the Gang of Eight, Rubio has so far kept a low profile on the controversial topic of immigration reform this month during the recess. 

Instead, he has focused on building grassroots support for a GOP plan to threaten a government shutdown unless President Obama’s healthcare law is defunded.

Rubio is seen as a possible 2016 GOP presidential contender, but his support among GOP voters has taken a hit after he backed immigration reform.
