President Donald Trump is set to make this third visit to Nashville since becoming the nation's 45th president.
Trump has a rally planned for Tuesday evening as he comes to Music City to headline a fundraiser for Republican Senate candidate Marsha Blackburn.
Here's what you need to know about his visit.
Why is President Trump coming?
The Blackburn Victory Fund announced earlier this month that Trump would headline a May 29 fundraiser for Blackburn in her bid to replace U.S. Sen. Bob Corker. She is facing former Democratic Gov. Phil Bredesen in what is a closely watched contest.
Then a Trump rally got scheduled for the same day at Nashville's Municipal Auditorium.
The victory fund is a joint fundraising committee composed of Marsha for Senate, MARSHA PAC and the National Republican Senate Committee.
When is Trump coming to Nashville?
Trump is expected to be in Nashville in time for a 7 p.m. rally at Municipal Auditorium. The location is the same place Trump held a rally when he visited Nashville in March.
What about the fundraiser?
A private roundtable with Trump for two costs $44,300 per couple, a private photo reception costs $10,800 per couple and a general reception with the president costs $2,700 per couple.
Why is Trump's visit a particularly big deal?
Blackburn, a Brentwood Republican and member of Congress, and Bredesen each face nominal opposition in their respective party primaries in the Aug. 2 election.
As a result, a de facto general election campaign is under way. And the race already appears close. Both candidates have high name recognition, according to a recent Vanderbilt University poll.
But Bredesen has far higher favorable ratings than Blackburn, the Vanderbilt poll found, and some other polls have shown the Democrat ahead of Blackburn in a head-to-head matchup.
This all adds up to a race that will generate a lot of buzz and attention, especially with Republicans holding a narrow 51-49 edge in the Senate.
Senate Majority Leader Mitch McConnell, R-Ky., recently named Tennessee as one of nine battleground states he believes will help decide control of the Senate in November.

What's the view of Trump in Tennessee?
Trump is visiting Nashville, an overwhelmingly Democratic city. But he continues to remain extremely popular in the state.
The recent Vanderbilt University poll put his approval rating at 53 percent, up from 48 percent in a similar survey conducted in December. He carried all but three counties in the 2016 election.
Finally, what are the other two Nashville visits?
President Donald Trump on Wednesday toured The Hermitage, the historic home of President Andrew Jackson, and placed a wreath on the seventh president's tomb. Trump, the first sitting president to visit since Ronald Reagan, toured the mansion and a somber Trump walked under to Jackson's tomb saluting and laying a wreath as Taps played in the background.
The visit by the 45th president is historic. Jackson's populist politics have resonated with Trump. Upon moving into the White House last month, the new president hung a portrait of Jackson in the Oval Office.
Trump came to Nashville in January to deliver an address to the American Farm Bureau Federation Convention at the Gaylord Opryland Resort & Convention Center.
In March 2017, he held the rally at Municipal Auditorium, but also visited The Hermitage, the home of Andrew Jackson, the nation's seventh president.
Trump had likened himself to Jackson and his populism and has hung a portrait of him in the Oval Office. Trump visited Jackson's tomb.
