A Democrats-only Hispanic caucus will formally invite two Latino Republicans to join their congressional caucus in the next couple of days after a week of "will they or won't they."

But there's a little catch: They could still vote to deny them membership.

Last week, the Congressional Hispanic Caucus balked at the idea of inviting Rep. Carlos Curbelo, R-Fla, to join their group. The caucus tabled the vote, deciding to ask the House Administration Committee for clarification about their bylaws. A number of members saw Curbelo's request to join as a "political move."

The caucus met on Thursday and decided to send invitation letters to Curbelo and fellow Florida Republican Rep. Illeana Ros-Lehtinen, a staffer with knowledge of the situation told the Washington Examiner. Curbelo is facing a tough re-election as Democrats are eager to flip his Miami-area seat and Lehtinen is retiring in 2018.

After the invites are sent, Curbelo and Ros-Lehtinen will have to accept and apply. Then, the Hispanic caucus will vote to either admit or deny them membership. Each of them will have to receive a majority of votes from the caucus, which is made up of 31 Democrats.

The Washington Examiner first broke the news that Curbelo's effort to join the group had stalled.

"If we don't have to let him in then why would we let someone in who goes against what we stand for?" Rep. Juan Vargas, D-Calif., told the Examiner on Wednesday.

Curbelo shot back on Twitter, calling the group's vote to table his invitation a "shameful position."

"It seems like for some in the @HispanicCaucus, some Hispanics are just not good enough," he said.
