Republican U.S. Sen. Mark Kirk has lagged far behind Democratic challenger U.S. Rep. Tammy Duckworth in raising money for the final weeks of his re-election bid.

Documents filed with federal election authorities this month show Kirk raised almost $1.2 million between July 1 and September 30.

Duckworth raised more than three times that amount, bringing in $4.1 million during the same period.

It was her strongest fundraising quarter yet, leaving Duckworth with $4.3 million cash on hand. Kirk's campaign fund had a balance of about $1.4 million.

Mitt Romney stumped for US Senator Mark Kirk in Chicago.   

The former presidential nominee says a Republican Senate could keep the president in check.

"It’s essential that we have a Republican Senate to keep the Senate and keep America from going off the rails," he said.

Both Romney and incumbent Senator Kirk say they won’t vote for Donald Trump.

Kirk says he and Romney share another similarity: both are Republicans who have won in states that tend to favor Democrats.

The Chicago Tribune has endorsed Democratic U.S. Rep. Tammy Duckworth for the U.S. Senate, arguing that incumbent Republican Mark Kirk is unable to fully do the job after recovering from a stroke.

The newspaper said Friday that "due to forces beyond his control, Kirk no longer can perform to the fullest the job of a U.S. senator."

Kirk spokesman Kevin Artl called it "a low-blow and cheap shot" that's "not based on fact or reality."

The two U.S. senate candidates criticized their own political party’s nominees for president.

Duckworth, a Democratic U.S. Representative, responded to an inquiry about  Hillary Clinton’s private email server.

"She needed to turn over those emails," Duckworth said. "We needed to make sure that things were more transparent. I do have real concerns."
