"The View" co-host Ana Navarro pressed former West Virginia Sen. Joe Manchin on Monday about why he did not endorse Vice President Kamala Harris in 2024.Navarro asked, "What was your issue with Kamala Harris, and now as you look back, and we are where we are, do you still stand by that decision?"Manchin said his opposition stemmed from Harris support for eliminating the Senate filibuster."I do, because she openly came out and said she would get rid of the filibuster," Manchin told the co-hosts.'THE VIEW' CO-HOST DESCRIBES HARRIS INTERVIEW AS 'MICROCOSM OF EVERYTHING THAT'S WRONG' WITH DEMOCRATIC PARTY"I know everybody has a different view. The filibuster is basically there to protect us from being singular, basically being a simple minority," he said. "If you're a simple minority with a 51-vote threshold, and all you need is one more, OK, if it's 50-50 here, and one person, that's 51%, that doesn't basically give you any cohesion the way you're going to have anything that'll last."Manchin argued the U.S. would risk flip-flopping on policy like "Europe" or other governments around the world."The Senate is the most unusual body. It was designed to be unusual," he added.Co-host Sunny Hostin pushed back on Manchin, noting Republicans had invoked the "so-called nuclear option."SUNNY HOSTIN FEELS 'TERRIBLE' ABOUT KAMALA HARRIS FUMBLING HER VIRAL QUESTION ABOUT DIFFERENCES WITH BIDENManchin reiterated that keeping the filibuster intact was the main reason he refused to endorse Harris.Harris said during a September 2024 interview that she supported eliminating the filibuster to pass abortion laws."I think we should eliminate the filibuster for Roe," Harris said on the "Wisconsin Today" show in September 2024. "And get us to the point where 51 votes would be what we need to actually put back in law the protections for reproductive freedom and for the ability of every person and every woman to make decisions about their own body and not have their government tell them what to do."CLICK HERE FOR MORE COVERAGE OF MEDIA AND CULTUREManchin retired at the end of 2024 after serving 14 years in the Senate.The former senator also announced last year that he was registering as an independent."However, since becoming aUnited States Senator in 2010, I have seen both the Democrat and Republican parties leave West Virginia and our country behind for partisan extremism while jeopardizing our democracy.Today, our national politics are broken and neither party is willing to compromise to find common ground. To stay true to myself and remain committed to put country before party, I have decided to register as an independentwith no party affiliation and continue to fight for Americas sensible majority," he said in May 2024.
