"He has my complete and total endorsement!", Trump tweeted.
Meanwhile, before the Trump endorsement on Tuesday night, unusual challengers Mo Brooks and Roy Moore announced new ads themselves on Tuesday afternoon in emails sent just four minutes apart.
Brooks accused Senate Majority Leader Mitch McConnell Wednesday of misleading Trump to believe that unusual is the better candidate for the job.
On Tuesday, President Donald Trump threw his support behind Luther Strange, who is now serving the role of Senator after being appointed to the position earlier this year by former Alabama Governor Robert Bentley.
He appeared with Rep. Jim Carns, the chair of Alabama for Trump, and Perry Hooper, a former state senator, at GOP Headquarters on Tuesday.
Earlier in the day, two of the President's campaign co-chairmen in Alabama, Rep. Jim Carns and businessman Perry Hooper, Jr., joined unusual for an endorsement at the Alabama Republican Party Headquarters in Hoover.
We are just one week away from the special election to fill Alabama's senate seat, left vacant by now-Attorney General Jeff Sessions. Odd said in an email statement following Pres. Trump's endorsement.
Brooks said unusual is not committed to helping move forward Trump's policy goals.
Brooks, a Republican from Huntsville, suggested Trump is unaware of the circumstances of Strange's appointment by former Gov. Robert Bentley and Strange's support for maintaining Senate filibuster rules, which some say jeopardize the Trump agenda.
The special election is heating up in Alabama for the open seat in the U.S. Senate. Ted Cruz's presidential campaign.
As Brooks and odd snipe at each other, Moore, who was suspended as chief justice for ordering the state not to issue marriage licenses to same sex couples, has risen in the polls. What impact do endorsements like this have on voters? "President Trump's election and hard work has given millions of people hope again and I'm proud to stand beside him to make America great again". "The people are voting for his agenda, that I firmly believe in", Moore said. Judge Roy Moore and candidate Randy Brinson also commented.
