- "I believe the majority of the Republicans in the US Senate are not going to vote for Donald Trump," McCaskill said.
- "[A] great number of them will in fact vote for Hillary Clinton," McCaskill added.
McCaskill, a top Clinton surrogate, added that many Republican senators are publicly supporting Trump but privately they are supporting Clinton.
"I believe, and I'm basing this on some of the things my colleagues have said to me, I believe the majority of the Republicans in the US Senate are not going to vote for Donald Trump because they know that they can work with Hillary Clinton and get some things done," McCaskill told radio host McGraw Milhaven on Missouri's KTRS.
McCaskill reiterated her statement after Milhaven asked her to clarify. "I believe that a great number of them will not be voting for Donald Trump, and a great number of them will in fact vote for Hillary Clinton," McCaskill said.
McCaskill criticized Trump for his inability to get along well with others, and argued that Clinton had worked well across the aisle with Republicans during her time in the Senate.
Also in the interview, McCaskill criticized FBI Director James Comey for his announcement Friday that the FBI was renewing its investigation of Clinton's private email server.
"It's really outrageous, because when you are in law enforcement, and as somebody who spent a number of years as a prosecuting attorney, one of the things that you are taught is that the most important thing is to stay married to the facts." McCaskill said, "And until you know what the facts are you should keep your mouth shut."
