"No, Bill Weld is in this for the long haul and beyond my wildest dreams Bill Weld is my running mate," Johnson said on CNN's "New Day."

ADVERTISEMENT "No, no chance Bill Weld drops out," he added later.

Johnson made the comments in response to CNN's Alisyn Camerota, who said there are reports that Weld, a former GOP governor of Massachusetts, is considering leaving the Libertarian ticket. She didn't attribute the reports.

"There are reports that your running mate, VP nominee Bill Weld, is considering actually dropping off the ticket because he's concerned at this point that a vote for both of you would deny Hillary Clinton a vote and therefore help elect Donald Trump," Camerota said.

Weld said in a statement to CNN on Sunday that he has no intention of dropping from the Libertarian ticket after CNN political commentator Carl Bernstein said sources told him Weld was considering dropping from the race if staying in might help elect Trump, the Republican nominee.

"Under no circumstances will our energies be diverted from our goal of winning the election and serving our country," Weld said.

Johnson and Stein have been performing well in polls for third-party candidates, though they appear to have little if any chance of winning the election. Both are polling less than 15 percent in polls and missed the cut for the first debate slated to be held Sept. 26 at Hofstra University, the Commission on Presidential Debates announced Friday.

Johnson has said he still thinks he can get into future debates.

"I'm polling higher right now than Ross Perot was when he was invited to do the first debate," Johnson told CNN on Monday.
