Sen. Marco Rubio is expected to appear at a closed door meeting next Tuesday organized by the Tea Party Caucus.
The Florida Republican, once a darling of the tea party, may face criticism from tea party supporters who have recently vocalized their dissatisfaction with the freshman senator's stance on immigration, Politico reported
Rubio, widely seen as a potential 2016 GOP presidential candidate, will be joined by other conservative GOP colleagues including Sens. Mike Enzi of Wyoming and Mike Lee of Utah, at an event that will bring together several conservative groups.
The Republican National Committee is also expected to send a representative to the meeting, according to Politico.
This will be the group's second meeting this year
which aims to gather lawmakers on both sides of Congress to discuss conservative policy responses on issues such as the IRS scandal, Benghazi and immigration reform.
