The vice chair of President Trump's voter fraud commission claims "we may never know" if Hillary Clinton won the popular vote.

MSNBC host Katy Tur asked Kris Kobach on Wednesday if the commission exists because Trump thinks he would have won the popular vote if it weren't for voter fraud.

Clinton, the Democratic nominee, won the popular vote in the 2016 election by about 3 million votes.

"That is not the reason that the commission was created," Kobach responded. "The commission is to look at the facts as they are, go where the facts lead us on voter fraud."

"So again, you think that maybe Hillary Clinton did not win the popular vote?" Tur asked.

"We may never know the answer to that question," Kobach said. "Let's suppose that the commission determined there was a certain number of votes cast by ineligible voters, you still won't know if they voted for Trump, Clinton or someone else."

"So, were the votes for Donald Trump that led him to win the election in doubt as well?" Tur said.

"Absolutely," Kobach responded.

Just days after his inauguration, Trump told lawmakers at the White House that 3 million to 5 million undocumented immigrants voted in the election, costing him the popular vote.

Trump's commission met for the first time Wednesday.
