Vice President Biden renewed his warning on Tuesday that the administration's agenda would come to a "screeching halt" if Republicans win control of Congress.

Biden said he was right to warn that the administration's work would be scuttled if the GOP manages to pick up enough seats in this fall's elections to win back the House, or possibly, the Senate.

"If these guys win, and I got in trouble for saying this early in the campaign," Biden explained at a rally at Penn State University, "if the Republicans take back the House and Senate, our entire agenda will come to a screeching halt."

"I was right then and I'm right now," the vice president added. "They're being straightforward about it; they're not hiding the ball."

The warning by Biden is meant to underscore the administration's efforts to turn out voters to protect the Democratic majorities in the House and Senate in November. He was in Happy Valley to urge the first-time and young voters who propelled President Obama into office in 2008 to turn out again for this fall's elections. Obama will make a similar argument later today at the University of Wisconsin at Madison.

Former President Bill Clinton made a similar warning to Democrats on Tuesday in a fundraising request for the Democratic Congressional Campaign Committee (DCCC), House Democrats' campaign arm.

"There's a simple reason why I am planning to spend the next five weeks crisscrossing the country, campaigning as hard as I can for House Democrats," wrote the former Democratic president. "Everything that you and I have fought for since 2006 is on the line."
