White House press secretary Sarah Sanders declined to say Thursday if President Trump is backing away from his endorsement of Sen. Luther Strange, R-Ala.

"Due to the legal restrictions that I have, I cannot answer anything political from the podium," Sanders told reporters. "So I have to leave that to outside folks and the president himself."

The Washington Post reported that Trump is considering being less engaged on behalf of Strange ahead of a Sept. 26 Republican primary runoff.

Strange placed second in an initial round of voting this month and is in a tight race with former Alabama Supreme Court Chief Justice Roy Moore, a fiery social conservative known for resisting federal court orders on a Ten Commandments monument and same-sex marriage.

Trump endorsed Strange in a series of tweets days before the first round. Moore still placed first, with nearly 39 percent — about six percentage points ahead of Strange.

Strange, previously Alabama's state attorney general, was appointed to fill Jeff Sessions' Senate seat in February by Gov. Robert Bentley while the governor was under investigation by Strange's office. Bentley later resigned and accepted a plea deal.

Establishment Republicans, including Senate Majority Leader Mitch McConnell, strongly support Strange and view him as a reliable vote. Moore is vowing to overcome Strange's institutional advantage, and polls suggest a close race.
