Democrat Kirsten Gillibrand is chipping in to help her party retain the House seat she left after being appointed to replace Hillary Rodham Clinton in the Senate. Gillibrand is featured in a new ad talking up businessman Scott Murphy, the Democratic nominee for the special election in New York’s 20th District.

“I’m asking you to elect Scott Murphy to fill my seat in the House,” Gillibrand tells District voters. “Scott’s the only candidate with proven business experience,” she added, reiterating a key plank in Murphy’s campaign. Murphy, 38, has never run for political office and is instead talking up his background as an investor and job creator.

Gillibrand, who remains highly popular in the district, formally endorse Murphy Feb. 14 at an event in Albany.
