Sen. Kirsten Gillibrand (D-N.Y.) has nabbed the backing of Rep. Jerrold Nadler (D-N.Y.), after all.

When Gillibrand was originally appointed to her seat, Nadler was out front with the criticism of her appointment, labeling her positions too conservative and saying that a lot of Democrats were "upset."

But now that her primary campaign appears to be relatively harmless, the resistant Nadler has come around to Gillibrand. He announced Monday that he will support her 2010 bid for the final two years of Hillary Rodham Clinton's Senate term.

“From protecting a woman’s right to choose and standing up for issues of pressing concern to the LGBT community, to fighting for a robust public health insurance option and protecting our environment by working to reduce harmful emissions, Kirsten Gillibrand has been a great partner on many progressive causes,” Nadler said. “We have worked closely together to provide our 9/11 heroes and affected community members with the health care and compensation they deserve, and on a variety of other issues facing our State and the Nation. New Yorkers want and need Kirsten on their side and I’m proud to endorse her for U.S. Senate.”
