A GOP operative told The Washington Post that Trump could distract from GOP messaging.
"Trump coming down to Georgia is the worst thing that can happen for Republican candidates down here," the operative told the Post.
"It immediately turns the focus from inflation and immigration to Donald Trump, and Donald Trump lost the last election here."
The Georgia race, considered one of the tightest in the country, has been called a toss-up by some experts, while poll averaging site FiveThirtyEight gives Warnock a slight edge.
Sources told the Post Trump may do several additional rallies before election day, including in Georgia, but only where he is wanted.
