Kristen Welker, an NBC News journalist, has been given the tough task of moderating the final US presidential debate between US President Donald Trump and Joe Biden, following a chaotic first head-to-head affair. The 44-year-old will be looking to bring order to the debate that will be held in Nashville, Tennessee.

Welker, NBC’s White House correspondent since 2011, is already under pressure from President Trump and his entourage, who claimed that she’s left-wing, an allegation they regularly throw at mainstream media figures, an AFP report stated.

“She’s a radical Democrat,” Trump told a rally in Phoenix, Arizona, on Monday. “She’s been screaming questions at me for a long time and she’s no good.”

Trump, 74, doubled down on Tuesday, saying that the parents of the first woman of color to host a presidential debate since 1992 were fervent Democrats.

In January, he had struck a different tone, congratulating Welker on becoming a regular co-presenter of NBC’s Weekend Today show.

“They made a very wise decision,” Trump said.

The Philadelphia-born news anchor registered as a Democrat in 2012 but is not affiliated to any political party currently.

Welker should have been following in the footsteps of Steve Scully who was scheduled to moderate the second debate before it was canceled because Trump refused to take part virtually.

Scully was later placed on administrative leave by cable network C-SPAN after lying about a tweet linked to the president. Trump claimed it showed that the scrapped debate was going to be “rigged.”

During the first debate in Cleveland, Ohio, the moderator struggled to bring the candidates to heel as Trump repeatedly interrupted Biden and the debate turned into a incoherent slanging match.

This time around, Welker, known for her calm demeanor and incisive questioning, will be helped by the muting of the candidates’ microphones when they are not answering questions.

Welker has chosen the six topics for discussion, as tradition dictates. They are: fighting COVID-19, American families, race, climate change and national security.
