President Trump thinks Roy Moore, GOP candidate for Senate in Alabama, should leave the race if allegations of inappropriate sexual contact with minors decades ago were proven true, White House press secretary Sarah Sanders said Friday.

But Trump also thinks the controversial former state supreme court judge shouldn't face destruction based off allegations alone.

"Like most Americans, the president believes that we cannot allow a mere allegation, in this case one from many years ago, to destroy a person's life," Sanders told reporters traveling with Trump to Vietnam on Friday.

"However, the president also believes that if these allegations are true, Judge Moore will do the right thing and step aside," she added. "Regardless, the president must and will remain focused on representing our country on his historic trip to Asia where he has been treated with great respect and made unprecedented progress in further strengthening alliances and promoting America's interests above all else."

The allegations against Moore have sent Republicans scrambling to determine whether he should drop out of the race for a U.S. Senate seat in Alabama or attempt to weather the explosive scandal until the special election next month. Moore is running for the seat vacated by Attorney General Jeff Sessions.

Trump initially backed the man appointed to fill Sessions' seat, Sen. Luther Strange, in the primary race. But Moore's insurgent challenge overwhelmed Strange's lukewarm base of support in Alabama, and Trump has since thrown his support behind the Republican Senate nominee.

Moore has been leading in the polls, but if he stays in and the new allegations sink him, Republicans would see their majority in the Senate fall to 51-49.
