After Judge Roy Moore won the Republican nomination for the Alabama senate race on Tuesday, President Trump stuck to his promise and endorsed Moore on Twitter Wednesday morning. The President said that Moore will help “Make America Great Again.”

Moore defeated Senator Luther Strange, who Trump originally endorsed, by nearly 10 points last night. At a campaign rally for Strange in Huntsville last week, President Trump promised to campaign for Moore against the Democrat if he was to win. It seems the President is doing just that, going all in for the Republican nominee.

Trump reportedly called Moore to congratulate him on Tuesday night. He told Moore, “I look forward to working with you,” during the call.

Trump also tweeted his congratulations to the Republican nominee on Tuesday night, telling him to WIN in December.

Roy Moore will face off against Democratic challenger Doug Jones in the special election on December 12.
