“David Weprin is the right choice for voters because he will fight to protect Medicare and Social Security and work to get our economy back on track,” Gillibrand said in a statement.

“David understands that the key to protecting the middle class is to fight against the Republican efforts to privatize Medicare and Social Security. I'm proud to endorse David Weprin and I look forward to working with him on behalf of the working families and seniors who call Brooklyn and Queens home.”

Gillibrand's endorsement comes as national Democrats are taking a greater interest in the race, after a Siena poll showed Republican Bob Turner within six points in the heavily-Democratic district.

But the two senators wouldn't appear to be too concerned just yet. Both endorsements came by press release, with neither senator having appeared with Weprin so far. Earlier this year, in the special election in New York's 26th Congressional District, Schumer and Gillibrand each traveled to western New York to appear with Kathy Hochul, who eventually upset a heavy Republican favorite.
