President Obama on Saturday called for the public to encourage Congress to pass immigration reform as the Senate is poised to hold a key vote on the Gang of Eight bill this week.

During his weekly address, the president called the Senate measure a "commonsense bill that would be an important step toward fixing our broken immigration system." Obama's endorsement of the measure comes as the Senate is marching toward a final vote to end debate on the immigration bill on Thursday.

In his address, Obama touted enforcement measures in the Senate bill that are aimed at strengthening security at the border, as well as its pathway to citizenship for the 11 million people living in the United States illegally. He also cited the Congressional Budget Office's recent estimate that found the Senate immigration bill will reduce the country's deficits by "almost a trillion dollars over the next two decades."

"So that’s what comprehensive immigration reform looks like. Stronger enforcement. A smarter legal immigration system. A pathway to earned citizenship. A more vibrant, growing economy that’s fairer on the middle class. And a more stable fiscal future for our kids," Obama said.

On Monday, the Senate will vote to end debate on a border security deal that is viewed as key to winning more GOP support for the immigration bill. The deal would double the number of border patrol agents and authorize the construction of 700 miles of fencing across the U.S.-Mexico border.

Supporters are aiming to win at least 70 votes in favor of the sweeping immigration bill, which would build momentum for immigration reform in the House.

The president acknowledged that the Senate's bill "isn't perfect," but said it represents a "compromise" that includes policy measures that he and others have advocated for in immigration reform.

"Nobody is going to get everything they want—not Democrats, not Republicans, not me. But it's consistent with the principles that I and others have laid out for commonsense reform," Obama said.

"That's why Republicans and Democrats, CEOs and labor leaders, are saying that now is the time to pass this bill."
