Sen. Joe Manchin (D-WV) revealed why he is not seeking a third-party bid for the White House this year, listing the Senate’s failure to pass a border and foreign aid bill as the “biggest” contributor.

Manchin, who announced he was not running for president on Friday, said the lack of bipartisan cooperation on the border deal despite the country’s border crisis was a major factor and blamed former President Donald Trump for the sudden change on the border deal.
