Sarah Palin on Monday came out against the Senate immigration bill, criticizing its border security provisions and labeling Sen. Marco Rubio (R-Fla.) an "amnesty supporter."

"It’s beyond disingenuous for anyone to claim that a vote for this bill is a vote for security," Palin wrote on her Facebook page. "Look no further than the fact that Senator Rubio and amnesty supporters nixed Senator [John] Thune’s amendment that required the feds to finally build part of a needed security fence before moving forward on the status of illegal immigrants who’ve already broken the law to be here."

Palin also criticized the decision to spurn so-called "trigger" provisions -- sponsored by Sens. Rand Paul (R-Ky.) and John Cornyn (R-Texas) -- that would halt the path to citizenship until certain border security benchmarks are met.

She said a new border security agreement, crafted by Sens. Bob Corker (R-Tenn.) and John Hoeven (R-N.D.) and set for a vote Monday, is inadequate.

"Now the Senate’s pro-amnesty crowd is offering a fig leaf to security via the Corker-Hoeven Amendment, but this is really nothing more than empty promises. It’s amnesty right now and border security … eh, well, someday," she wrote.

Palin also targeted Rubio in a tweet Sunday, linking to an article on conservative that argued Rubio has foresaken his past opposition to amnesty -- specifically during his 2010 campaign.


Palin also suggests that opposition to the bill could be a "rallying cry" for conservatives in the 2014 midterm elections.

"For just as opposition to Obamacare became a rallying cry for the 2010 midterm elections, opposition to this fundamentally transforming amnesty bill will galvanize the grassroots in next year’s elections," she said. "And 2014 is just around the corner."
