Video has emerged showing incoming White House Chief of Staff Mick Mulvaney trashing Donald Trump as a 'terrible human being' during the 2016 election.

The video, which surfaced on Friday just hours after Trump named Mulvaney to fill the post that will be vacated by John Kelly, shows Mulvaney at a public forum days before the election.

Then a Republican Congressman, Mulvaney was running for re-election to South Carolina’s 5th District when he and his Democrat challenger made their last-minute appeals to voters at the forum.

'Do I like Donald Trump? No,' says Mulvaney in the video, which was first reported by the Daily Beast. 'Is he a role model for my sons? Absolutely not.'

Mulvaney went on to say that Democratic presidential candidate Hillary Clinton was even worse, both personality and policy-wise, and that he was throwing his support behind Trump's candidacy despite the Republican's shortcomings.

'Yes, I'm supporting Donald Trump. I'm doing so as enthusiastically as I can given the fact that I think he’s a terrible human being,' Mulvaney said.

Mulvaney's remarks were reported at the time by local newspaper The State, but the video did not surface online until Friday.

He went on to win his re-election handily, but resigned to become Trump's director of the Office of Management and Budget.

Trump said Friday in tweets that Mulvaney will lead the West Wing until he can find a permanent replacement for Kelly.

A senior official indicated that Mulvaney's tenure will be indefinite, however, telling reporters at the White House minutes after the announcement, 'There’s no time limit.'

Just that morning, the White House was claiming that Kelly could stay longer than planned, having already agreed to extend his tenure longer than Trump initially said to ensure a smooth transition.

Trump said in an early evening tweet that he had changed his mind and Kelly would be departing at the end of the year.

'I am pleased to announce that Mick Mulvaney, Director of the Office of Management & Budget, will be named Acting White House Chief of Staff, replacing General John Kelly, who has served our Country with distinction. Mick has done an outstanding job while in the Administration,' he announced.

Hours later he sent a follow-up tweet insisting 'MANY' people wanted the job.

Mulvaney has a lot on his plate as Office of Management and Budget head. A White House official said Friday that his job at OMB will be filled by his deputy Russ Vought

In naming Mulvaney, the president went on to say, 'I look forward to working with him in this new capacity as we continue to MAKE AMERICA GREAT AGAIN! John will be staying until the end of the year. He is a GREAT PATRIOT and I want to personally thank him for his service!'

Mulvany still heads the Office of Management and Budget, OMB, within the White House and earlier this year wore two hats as he filled the top job at the Consumer Financial Protection Bureau.

OMB would oversee a partial government shutdown in the case that Congress and the president are unable to resolve their differences ahead of a Dec. 21 deadline to pass legislation to pull unfunded areas of the government out of limbo.

Trump was said on Friday to be shopping a two-week delay in hostilities after declaring on Tuesday that he would 'absolutely' preside over a shutdown until Congress approves $5 billion for his border wall.

That would push the fight that could furlough federal workers over the Christmas holiday into early next year. Trump will have lost much of his leverage by then, as Democrats take the majority in the House, but as he made clear in a Thursday tweet, he now sees the value of avoiding an expensive and potentially toxic government closure.

'Let’s not do a shutdown, Democrats – do what’s right for the American people!' Trump had tweeted.

His appointment of Mulvaney to Kelly's post on Friday evening suggests that Trump, whose White House is already stretched thin, is seriously considering his options.

A senior official told reporters on Friday evening that the OMB job will be filled for now by Mulvaney's deputy Russ Vought. The White House has since clarified that Mulvaney will remain OMB head and Vought will merely manage the day-to-day operations of the budget office.

The official who briefed press on Friday stressed Mulvaney's credentials for chief of staff as a former Member of Congress, who served from 2011 until the president appointed him OMB head.

'He knows Congress. He knows Capitol Hill,' the official said.

Mulvaney and Trump met at the White House on Thursday afternoon prior to the announcement to discuss the impending fiscal cliff. Trump said in a tweet hours later that Mulvaney would be his interim chief of staff.

Hours prior to the president's announcement that Kelly would be succeeded by Mick Mulvaney, the White House said Trump son-in-law Jared Kushner was not under consideration. Kushner is Ivanka Trump's husband and a senior adviser to the president like she is

Trump promoted the job as a temporary assignment, but White House officials signaled that Mulvaney could fill the position for an extended period of time.

'He’s the acting chief of staff, which means he’s the chief of staff,' a senior official who requested anonymity said. 'He got picked because the president liked him they get along.'

The person said that Mulvaney was named 'acting' chief instead of permanent chief, 'because that’s what the president wants.'

'We’ll see,' a second official said of the appointment. 'It’s what the president wants right now.'

Prior to holding federal office, Mulvaney served as a state representative and state senator in South Carolina. Before that, he practiced law and worked for his family real estate business.

Mulvaney and his wife Pamela have three children.

In Congress, he was known as a fiscal-hawk and social conservative who ran with the right-wing Freedom Caucus and was willing to shut the government down to trim down the federal deficit.

Since joining the Trump administration he has taken flack for claiming that there is such a thing as a 'good shutdown' that could permanently fix the appropriations process. He has also been dogged by a claim that he says was meant to be a joke that he would only meet with lobbyists as a congressman who'd contributed to his campaigns.

Chris Christie became the latest contender for chief of staff to take himself out of the running on Friday, saying in a statement that it is an honor to have been considered, but it's not the right time in his life for the assignment

Mulvaney was the obvious choice for acting White House chief of staff after having been one of two rumored picks for the position for close to six months.

The other contender, Nick Ayers, turned the job down last weekend.

Chris Christie also took himself out of the running, saying in a Friday afternoon statement that it is an honor to have been considered, but it's not the right time in his life for the assignment.

He told the New York Times that he had asked Trump 'to no longer keep me in considerations for this post' following a meeting on Thursday to discuss the position.

Counselor to the president Kellyanne Conway meanwhile confirmed that Trump son-in-law Jared Kushner was not under consideration.

'I haven't heard either Jared or the president mention Jared on the list,' she asserted. 'But I think he's doing a great job at what he's doing.'

Asked whether the president spoke to Christie and what exactly happened she said: 'I do know the answer, but I can't comment. They had a great meeting last night.'

She smiled and said nothing as DailyMail.com asked if she is interested in doing the job that no one else seems to want.

Kushner's potential candidacy emerged shortly after the president claimed he had five candidates who actually want the job fighting it out.

'Five people. Really good ones. Terrific people. Mostly well known, but terrific people,' Trump told reporters on Thursday.

The claim was met with skepticism in wider Washington D.C. given that Trump pushed out Kelly without a successor in place and was turned down by his first choice.

Trump told the only Republican openly expressing interest in the job that he wants him to stay in Congress this week.

A White House statement on Wednesday said that Trump ruled out North Carolina Rep. Mark Meadows for the top White House position.

'Congressman Mark Meadows is a great friend to President Trump and is doing an incredible job in Congress. The President told him we need him in Congress so he can continue the great work he is doing there,' White House press secretary Sarah Sanders said.

Trump's plans were turned upside down when Trump's first pick for the position, Nick Ayes, unexpectedly turned the president's proposition down.

The White House subsequently said that Kelly would be staying on until early January 'at least' to the manage the West Wing while the president conducts his search for a replacement.

The president claimed Tuesday that more than 10 people were competing for the chief of staff job but none appeared to be in the lead and it was unclear how much any of them actually wants to do it.

'We are in no rush. Over a period of a week or two or maybe less we'll announce who it's going to be, but we have a lot of people who want the position,' Trump said in a Oval Office meeting with Democratic leaders on Tuesday morning that Kelly attended.

He said, 'A lot of friends of mine want it. A lot of people that Chuck and Nancy know very well want it, I think people you'd like,' Trump said, talking up the post. 'We have a lot of people that want the job of chief of staff. So we'll be seeing what happens. We're in no rush.'

Kellyanne Conway told reporters this week that Kelly will stay on as chief of staff 'at least' through the beginning of the year

The reason, Trump said: 'Because we have a wonderful chief of staff right here.'

Conway had said during an appearance on 'Fox & Friends' on Tuesday morning – just days after the White House said Kelly's tenure was nearly over – that he wouldn't be leaving at the end of the year as planned.

'He will stay on the job through January 2nd at least, and I think there were will be a very peaceful and pragmatic transition to the next chief of staff,' Conway said. 'But the president has many people who want to serve here.'

Later in the day, the president held a bill signing in the Oval Office that Mulvaney and Meadows were a part of. The two men allegedly competing for the same job who worked closely together in Congress stood side by side as the president talked.

By Wednesday afternoon, the White House had announced that Meadows, at least, was out of the running, and on Friday, ex-congressman Mulvaney appeared to be the last candidate standing.
