President Donald Trump will spend part of the final Sunday before next week's midterm election in Tennessee one more time, announcing plans to hold a campaign rally in Chattanooga.

The visit will mark Trump's third trip to Tennessee this year to stump for Republican U.S. Senate nominee Marsha Blackburn and his fifth overall trip to the Volunteer State since becoming president.

Trump's visit to Chattanooga is set for McKenzie Arena, but an exact time on Sunday has not been disclosed.

The Trump campaign confirmed the visit in a news announcement Wednesday after days of rumors and reports about the Chattanooga visit.

“President Trump considers Tennessee to be critical for GOP victory in the midterms, so as we complete the race to the finish he will urge Tennesseans to deliver for America on Election Day,” Michael Glassner, chief operating officer of Trump's campaign committee, said in a statement.

The president's appearance is a sign of a tight race in Tennessee, one that Trump and Republicans have identified as key to retain control of the U.S. Senate.

Trump is also set to visit the Senate battleground states of Florida, Missouri, West Virginia, Montana and Indiana in the final week before the Nov. 6 election. Each are states that Trump carried in 2016 and where his approval rating remains strong.

Blackburn has campaigned aggressively as an unapologetic ally of Trump's agenda while casting Democratic nominee Phil Bredesen as a threat to Trump's vision. Bredesen, former Tennessee governor, has disputed that characterization as he runs as an independent often at odds with his own party.

“Tennesseans from all walks of life support President Trump's agenda, and they are so excited he is returning to our state," Blackburn said in a statement. "We look forward to welcoming him back to Tennessee and having him on the campaign trail with us.”

Bredesen campaign spokeswoman Alyssa Hansen called Trump's visit a "perfect opportunity" for Trump to sit down with Bredesen to discuss their "shared interest in lowering prescription drugs prices."

"As skilled businesspeople, they can work together to get the best deal for Americans. Gov. Bredesen's plan to tackle prescription drug prices illustrates what he's said from day 1 — he will work with President Trump to get things done for Tennesseans because that's what Senators ought to do."

Also on Sunday, Trump will be in Macon, Ga. — about 200 miles from Chattanooga — for a 4 p.m. EST campaign rally. Georgia is home to a competitive governor's race between Democratic Stacey Abrams Republican Brian Kemp.

It's unclear if Trump's Chattanooga visit will occur before or after his Georgia appearance.

Trump in September held a campaign rally in Johnson City after previously stumping for Blackburn in Nashville in May.
