Another former presidential candidate has announced an endorsement of Roy Moore for Alabama's vacant Senate seat.

U.S. Sen. Ted Cruz, R-Texas, announced his backing of Moore in a blog post on Tuesday.

Former Arkansas Gov. Mike Huckabee, who twice has run for president, has also endorsed Moore.

Moore faces Democrat Doug Jones in the Dec. 12 election.

In his post, Cruz said that the Senate needs "reinforcements."

Cruz's full statement:

"This December, the people of Alabama have a clear choice.

"They can choose a liberal Democrat, who will stand with (Senate Minority Leader) Chuck Schumer to raise taxes, weaken our military, open our border, and undermine our constitutional rights. Or, they can choose to elect Judge Roy Moore, a conservative who will proudly defend Alabama values.

"I strongly urge the voters to elect Judge Roy Moore. Judge Moore has a lifelong passion for the Constitution and the Bill of Rights, and he has the courage of his convictions.

"In the Senate, we need reinforcements; we desperately need strong conservatives who will stand up to the Washington status quo.

"Please join me in supporting Judge Moore on December 12."

Cruz also linked to Moore's campaign site in three different places in his post.

"Ted Cruz has been a stalwart defender of our constitutional rights," Moore said in a statement. "I appreciate his strong endorsement and I look forward to collaborating with him on proposals to strengthen the U.S. military, cut spending, and lower taxes on American families and businesses."
