The New York Times reported Wednesday that several members of the former vice president's campaign approached a senior Klobuchar aide at a dinner this week and broached the possibility of an alliance in which supporters from the two campaigns would bolster each other's numbers in Iowa precincts where one was not viable.

But the senior Klobuchar aide, Pete Giangreco, reportedly dismissed the effort led by Biden's Iowa state director, Jake Braun. The senator's campaign told the Times that it had no intention of working with rivals in Iowa or elsewhere.

“Our campaign is on the rise,” said Tim Hogan, Klobuchar's communications director. “We’ve never made caucus deals with other campaigns and don’t intend to.”

Biden's campaign declined to comment to the Times when contacted about the story.
