Donald Trump offers full support for controversial Republican Roy Moore

U.S. President Donald Trump gave embattled RepublicanSenate candidate Roy Moore a vigorous formal endorsement Monday, looking past allegations of sexual misconduct with Alabama teenagers as Republican leaders in Washington, once appalled by Moore's candidacy, began to come to grips with the ever-clearer possibility of his victory.

Buoyed by the taste of his own success in Congress as the Republican tax bill inches closer to passage, Trump telephoned Moore to offer encouragement as well as support and also argued in a pair of tweets that Moore's vote was badly needed to push the president's policies forward. The Republican National Committee quickly followed suit, announcing they were returning the support they had pulled last month.

In addition, Senate majority leader Mitch McConnell, who was initially among several national Republicans to urge Moore to drop out of the race, said Sunday it was up to Alabama voters to decide whether the former state Supreme Court chief justice should be elected.

Weeks ago, when accusations of sexual misconduct with teenagers first surfaced, Trump's spokespersonhad said the president believed Moore would "do the right thing and step aside" if the allegations were true.

'Go get 'em, Roy!'

Top Republicans vowed to expel him from the Senate if he won his Dec. 12 special election. And, publicly and privately, Republicanleaders described the allegations against Moore as credible and insisted there were no circumstances under which he should serve in the Senate.

Trump's tweets on Monday showed his thinking has evolved as Moore has rejected his party's appeals and doggedly remained in the race.

In the phone call, Moore said, Trump offered "his full support and said he needs a fighter to help him in the US Senate."

Moore tweeted that the president told him: "Go get 'em, Roy!"

Potentially explosive clash

Trump's move was somewhat symbolic: He had already all but endorsed Moore, repeatedly criticizing Democratic rival Doug Jones on Twitter and planning a campaign-style rally in Pensacola, Fla., on Friday, less than 32 kilometresfrom the Alabama border and just four days before voters head to the polls.

Still, Trump's decision to do away with any pretense of distance made clear he is increasingly confident in Moore's chances of victory despite the continued unease of some other Republican leaders.

And the RNC quickly followed his lead. An RNC official confirmed late Monday that the committee would once again be supporting Moore, after severing its fundraising ties to his campaign last month. It was not immediately clear what that support would entail. The official spoke on condition of anonymity to confirm the reversal, which was first reported by Breitbart News.

A Moore victory would set up a potentially explosive clash with fellow Republicans in Congress, some of whom have resoundingly called on him to quit the race. While some have softened their rhetoric recently, others have said they still will try to expel him if he is elected.

'We need his vote'

Moore's campaign was wounded by accusations this fall of sexual misconduct, decades ago, made by women who were then teenagers. One of the women alleges he initiated sexual contact when she was 14.

Moore denies it all, saying "I do not know any of these women. I did not date any of these women I did not engage in any sexual misconduct with anyone."

Trump, who has repeatedly noted Moore's denials, took a more political stance on Monday.

"Democrats refusal to give even one vote for massive Tax Cuts is why we need Republican Roy Moore to win in Alabama," Trump tweeted. "We need his vote on stopping crime, illegal immigration, Border Wall, Military, Pro Life, V.A., Judges 2nd Amendment and more."

'That's the only Republican'

In that same vein, longtime Alabama SenatorRichard Shelby said Trump's endorsement didn't surprise him. He said of the president, "I think he's interested, a lot of us are, in the numbers, being a Republican."

And SenatorOrrin Hatch, who travelled with Trump on Monday to Hatch's home state of Utah, said he realistically didn't have any choice. Hatch said, of Moore, "That's the only Republican you can possibly get down there at this time."

Trump first appeared to back Moore after his first choice, SenatorLuther Strange, lost the Republicanprimary for the seat once held by Attorney General Jeff Sessions. But the president went silent after The Washington Post reported on the allegations of sexual misconduct with two teens, ages 14 and 16, and efforts to date several others while Moore was a local prosecutor in his 30s.

By late last month, however, with pressure mounting from his former chief strategist Steve Bannon and other corners of his base, Trump was making clear that he preferred Moore, raising doubts about the candidate's accusers and criticizing Democrat Jones as the "liberal puppet" of Democratic leaders Chuck Schumer and Nancy Pelosi.

'The Senate should vote to expel'

Meanwhile, Moore himself was strongly criticized by top Republicans, including Cory Gardner of Colorado, chairof the Senate Republicancampaign apparatus known as the national Republican senatorial committee.

"If he refuses to withdraw and wins, the Senate should vote to expel him, because he does not meet the ethical and moral requirements of the United States Senate," Gardner said three weeks ago. He said last week he stood by that statement.

Jones, the Democrat, sidestepped questions about Trump's endorsement while suggesting the support of national Republicans like McConnell could do more harm than good in Alabama.

Project Veritas' plan to infiltrate Washington Post backfires: Callum Borchers of the Washington Post talks to Diana Swain about his colleagues' reporting that exposed a failed effort to infiltrate the newspaper. Watch The Investigators Saturdays at 9:30 pm ET and Sundays at 5:30 pm ET on CBC News Network.

"Our campaign is going straight to the people of the Alabama because that's who my voters are. It's not the president, it's not Mitch McConnell," Jones told reporters outside a steel mill in suburban Birmingham. "Obviously Mitch McConnell has very little credibility in this state anyway, so I'm not worried about him at all."

Expelling a senator is no easy task. The Senate ethics committee would have to investigate, and a recommendation of expulsion could take years.
