Schatz, D-Hawaii, left, talks to reporters about their effort to renew the ban on plastic firearms that can evade airport detection machines, at the Capitol in Washington, Monday, Dec. 9, 2013. Racing against a midnight deadline, the Senate gave final congressional approval Monday evening to a 10-year extension of the prohibition against guns that can slip past metal detectors and X-ray machines. WASHINGTON (AP) - A leading Senate Democrat says its "safe to say" a compromise budget bill avoiding a government shutdown will pass the Senate this week. New York's Chuck Schumer says he believes most members of his party will back the $85 billion legislation and at least four Republicans will join them on passage. Supporters say they want to get it to President Barack Obama's desk before lawmakers break for the holidays. Schumer tells MSNBC Senate Republican Leader Mitch McConnell of Kentucky won't let the legislation "go down." Schumer acknowledges Democrats are disappointed there's no extension of unemployment benefits, but says that will likely be taken up in a separate bill. He calls the House bill "a breakthrough" in the gridlock that has limited much of Congress's legislative acumen in recent years.
