WASHINGTON, D.C. (WPIX) -- Just call her senator. Kirsten Gillibrand, 42, was sworn in on Capitol Hill Tuesday as New York's new junior senator.

Vice-president Joe Biden administered the oath of office at 12:33 p.m.

New York's senior senator Chuck Schumer, joined the Gillibrand family to witness her become the youngest member of the August Body.

"I feel incredibly grateful that the governor placed his trust in me, she said. "To have the opportunity to serve this entire state at a time of great economic crisis is an extraordinary responsibility and I take that responsibility seriously."

A new Marist poll finds 46% of New Yorkers support the Gillibrand appointment, while 24% believe she's the wrong choice. Also, 30% say they are neutral on Govenor paterson's pick.

Marist conducted phone interviews yesterday with 611 registered voters. The margin of error is +/- 4%.

Meanwhile, Paterson's critics continue to blast him over the botched handling of the Gillibrand selection that ended with Caroline Kennedy withdrawing her name from consideration.     

State Senate Minority leader Dean Skelos stopped short of calling the governor a liar over the Kennedy debacle, adding Paterson spent more time grabbing media attention than on the business at hand.
