Two days after Democrat Doug Jones released a campaign ad saying he could work with Republicans better than Roy Moore, Alabama's Republicans in the U.S. House of Representatives gave their endorsement to Moore.

The six Republicans said they would support Moore, his campaign announced Thursday.

Congress members Robert Aderholt of Haleyville, Mo Brooks of Huntsville, Bradley Byrne of Fairhope, Gary Palmer of Birmingham, Martha Roby of Montgomery and Mike Rogers of Saks released a joint statement backing Moore.

Alabama's lone Democrat in Congress, U.S. Rep. Terri Sewell of Birmingham, is supporting Jones.

Voters go to the polls on Dec. 12 to determine who will fill the seat vacated by U.S. Attorney General Jeff Sessions. U.S. Sen. Luther Strange has been appointed to fill the seat until a senator is elected.

"Alabama Congressional Republicans have a long history of working together on issues that matter to our state," the representatives said in the statement. "We support the Republican nominee for Senate, Judge Roy Moore, and are confident his election will help us deliver conservative results.

"The House has passed bills repealing Obamacare, repealing Dodd-Frank, funding border wall construction, rebuilding the military, defunding Planned Parenthood, and we are working on pro-growth tax reform right now. At this critical time for our country, we need more conservative Republicans in the Senate, not fewer, to help us get legislation to President Trump's desk."

In a campaign ad released this week, Jones touted his ability to work with members of either party.

"I'll work across party lines to create jobs and get wages up," Jones said in the ad. "Fix health care so it really is affordable and give our children a first-rate education.

"And I can work with Republicans better than Roy Moore can work with anyone, and get it done."

In the announcement on the endorsements, Moore said he would "work closely" with President Trump as well as Alabama's congressional delegation.

"President Trump and Congressional Republicans have begun rolling back the jobs-killing regulations of the Obama era, and if I am elected to the U.S. Senate, I will work closely with the President and our Congressional team to support our workers and business owners in Alabama," Moore said.

Moore then pointed to critical industries in different parts of the state that, if elected, he would work to promote and protect.

"Our state is a place of entrepreneurial innovation, and we need a pro-business Senator who supports the jobs growth-agenda of President Trump," Moore said. "We must protect the coal and mining jobs, while keeping our workers safe, that are so essential to west Alabama and we must eliminate burdensome regulations on our Gulf Coast fishing companies.

"As a West Point graduate and a proud Army veteran, I understand, too, the vital role that the national defense industry plays in the Huntsville area and across the state. Alabama's defense contractors serve our nation and employ thousands of Alabamians. I look forward to working with our House members in D.C. to promote the defense industry and also ensure Alabama's military bases are protected when the Department of Defense goes through its next base realignment and closure evaluation."
