Senate Republicans sought to build momentum on Friday after successfully forcing Senate Majority Leader Harry Reid (D-Nev.) to beg off a $1.1 trillion omnibus spending bill.

Sen. John Cornyn (Texas), the chairman of the National Republican Senatorial Committee, wrote a valedictory e-mail to GOP supporters cheering the death of the omnibus bill.

"You did it. Facing pressure from you, Senate Majority Leader Harry Reid announced Thursday night he was withdrawing the Democrats' last-minute, 2,200-page-long, $1.1 trillion spending bill," Cornyn wrote, crediting Republican wins in Senate races this fall for the victory.

Reid pulled the spending bill from the Senate floor after Republicans signaled they would not support the legislation, despite some of the earmarked projects contained within the bill that different GOP senators had requested.

The top Senate Democrat said instead that he'd look to move a continuing resolution, which would keep spending at current levels for the next two months, and effectively punt on the spending issue until next year, when new Republicans are sworn in to Congress.

Cornyn sought to build momentum off of the defeat, which conservatives cheered as it was announced on Thursday evening.

"This is just the beginning though. We have to keep the pressure up because they will try again. We must keep the pressure up today, tomorrow, next month and for the next two years," Cornyn wrote, asking readers to sign a petition. "Will you continue to stand with us? Will you commit to holding the Democrats accountable and working to make sure Republicans take back the Senate in 2012?"
