President Obama will meet with business leaders Monday at the White House to rally support for the Senate immigration bill ahead of this week's expected vote.

The president will meet with nine executives at the 2 p.m. Roosevelt Room event, including former AOL Chairman Steve Case, Ethan Allen CEO Farooq Kathwari, and Chobani yogurt founder Hamdi Ulukaya.

According to a White House official, the president will detail to the group the projected economic benefits of passing the comprehensive reform bill.

"Business owners will meet with the president to discuss the importance of fixing our broken immigration system — and making sure that every worker in America is playing by the same set of rules and paying taxes like everyone else," the official said.

The meeting comes just hours before the Senate plans to hold a vote on the so-called "border surge" amendment, which would significantly increase both federal officers and technology deployed at the border.

Pro-immigration reform advocates are hopeful the measure will help draw Republican support in the Senate.

The amendment vote is seen as a proxy for the larger immigration reform bill, with supporters hoping to win in the neighborhood of 70 votes. Senate leaders hope that a bipartisan bill with significant support would force the GOP-controlled House to move forward with immigration legislation of their own.

"The bill will pass. I think we're on the verge of getting 70 votes. That is my goal," Graham said on "Fox News Sunday." "We're very, very close to 70 votes. The Hoeven-Corker amendment I think gets us over the top."

On Friday, White House press secretary Jay Carney heralded the amendment as "a breakthrough on the bipartisan effort."

"We’re certainly pleased that Republicans and Democrats continue to work together towards common-sense immigration reform," Carney said.
