Many Democrats are balking at holding meetings with Supreme Court nominee Brett Kavanaugh, saying they want more documents from his service in the George W. Bush White House.

Two vulnerable red-state Democrats -- Sen. Joe Donnelly (Ind.) Sen. Heidi Heitkamp (N.D.) -- are meeting with Kavanaugh Wednesday.

West Virginia Sen. Joe Manchin was the first Democratic senator to sit down with Kavanaugh a few weeks ago.

Sen. Elizabeth Warren (D-Mass.) is warning that the confirmation battle is far from over.

Speaking Tuesday on "Late Night With Seth Meyers," Warren said Kavanaugh's confirmation is "not a done deal."

Fox News analyst Marie Harf said Wednesday on "Outnumbered" that while it's not unfair of Democrats to ask questions about Kavanaugh's judicial philosophy, he will ultimately be confirmed.

"I don't think this is a politically advantageous fight for Democrats to draw out through the midterms," she said.

Melissa Francis added that Supreme Court justices are a big deal to many Americans, even though it's not that exciting to analyze.

"For people that are hardcore about politics, it's what they vote on," she said.

It was announced last week that Kavanaugh's confirmation hearing before the Senate Judiciary Committee will be held early next month.
