Declaring “the time for excuses is over,” President Barack Obama on Saturday trumpeted the economic benefits of an immigration overhaul, arguing that a bipartisan bill picking up steam in the Senate would put the nation’s loathed deficits and fragile entitlements on better footing.

A recent analysis from the Congressional Budget Office, lawmakers’ nonpartisan scorekeeper, was Exhibit A in Obama’s weekly radio and Internet address. The report shows deficits would fall nearly $1 trillion over two decades after the bill becomes law.

What’s more, Obama said, the influx of immigrant-driven investment, technology and businesses would give the economy a shot in the arm.

“This bipartisan, common-sense bill will help the middle class grow our economy and shrink our deficits, by making sure that every worker in America plays by the same set of rules and pays taxes like everyone else,” he said.

Confidence that the overhaul could pass the Senate by impressive margins is growing, and leaders scheduled a test vote on the bill for Monday, with a final vote expected by the end of next week.

In the Republican address, Rep. John Kline of Minnesota says Obama must show leadership to avoid an impending hike on student loan interest rates. He said it’s fortunate that Obama and House Republicans agree on the issue and have both proposed plans that would tie interest rates to the market. He accused Senate Democrats of blocking each plan.
