During his speech Friday night, Trump also urged voters to choose embattled Republican candidate Roy Moore in next week's Alabama Senate race despite sexual misconduct allegations.
He said Doug Jones will be "completely controlled" by the Democrats and declared that they need someone in that Senate seat who will support his agenda.
Trump, who overcame allegations of sexual misconduct to win last year's presidential election, looked past the charges against Moore and formally endorsed the former Alabama judge this past week for the seat once held by Jeff Sessions, now USA attorney general.
President Donald Trump returned on Friday to one of the pivotal states that gave him the presidency past year, even while delivering a message to its neighbor to the west: Reject Democrat Doug Jones in the Alabama Senate race.

Republican Senatorial candidate Roy Moore speaks during a campaign event at Oak Hollow Farm on December 5 in Fairhope, Alabama. "Ah, what are we gonna do - Gloria Allred, anytime you see her, you know something's going wrong".

"We can not afford, the future of this country can not afford to lose the seat", Mr Trump said, referring to his party's razor-thin 52-48 advantage in that chamber of Congress.

White House spokesperson Raj Shah said the president and White House have made clear that the Moore allegations are "troubling and concerning" and "should be taken seriously". But in the end, it is the vast majority of Alabamans who have always voted Republican who must examine their consciences.
"You don't even want to say people", Mr Trump said.
