The U.S., on Wednesday, will witness the final debate between its two presidential candidates: Republican nominee Donald Trump and Democratic nominee Hillary Clinton. The debate will feature Fox News’ Chris Wallace as the sole moderator.

Trump accused the moderators of the previous debates — NBC’s Lester Holt, CNN’s Anderson Cooper and ABC’s Martha Raddatz — of bias. It remains to be seen if Wallace will be added to this list.

The three-time Emmy award-winning journalist joined Fox News in 2003 and is host of “Fox News Sunday.” In 2006, the Washington Post revealed that the 69-year-old is registered as a Democrat but he told the Post this was more for practical purposes rather than political affiliations.

In Washington D.C, primary voting is open only to people registered with a party, hence Wallace said he was a registered Democrat so he could participate in the voting process.

“If you want a say in who’s going to be the next mayor or councilman, you have to vote in the Democratic primary,” Wallace said, adding that the Democratic Party is “really the only one” in Washington D.C.

However, he said he has voted for both Republicans and Democrats and does not believe that journalists shouldn’t vote, unlike Cooper. Cooper revealed in an interview earlier this year that he does not vote as he doesn’t want to have a personal stake in the election he is covering.

Speaking to radio host Howard Stern, Cooper said, “I don’t think I'm going to vote; I don’t think reporters should vote. It’s a thing ... There have been years where I have voted because sometimes I thought maybe I should ... I’ve gone back and forth on it.”

“I don’t want to be influenced one way or the other ... I believe people should vote, but ... my role is to ask questions,” he added

But Wallace told the Post that he finds the idea of journalists not voting “a little silly.”

“Look, some people think [journalists] shouldn't vote at all -- I think that's a little silly… However, I vote personally, I think I’m professional enough that it doesn’t have anything to do with the way I cover the news,” he said.

Wallace, in an interview in September, said he would not fact-check what the candidates say but would dedicate himself to strict time-keeping.

“That’s not my job,” Wallace reportedly said. “I do not believe that it’s my job to be a truth squad. It’s up to the other person to catch them on that. I certainly am going to try to maintain some semblance of equal time if one of them is filibustering, I’m going to try to break in respectfully and give the other person a chance to talk.”

The third and final presidential debate will begin Wednesday at 9 p.m. EDT at the University of Nevada in Las Vegas. Most major networks will carry a livestream of the 90-minute debate, which will focus on topics like immigration, the economy, debt and entitlements, and the Supreme Court, among others.
