Sen. Joe Manchin (D-W.Va.) called out Senate Minority Leader Harry Reid (D-Nev.) on Monday, saying his leadership didn't work.
"Well first of all, Harry's a good man," Manchin said while appearing on MSNBC’s "Morning Joe." "His leadership and the things he thought would work did not. So with that, you just move on."
In March, Reid announced he would be retiring in 2016. Reid has led the Senate Democrats since 2005 and has served in the U.S. Senate since 1987.
Manchin recently announced he would seek another term in the Senate and will not run for governor of West Virginia.
"Me walking away, I think, would be much worse when I have a chance to make a difference," Manchin said.
The top issue Manchin said he wants to address in the Senate going forward is drug abuse.
"It's just devastating in my state. It's killing families. ... This drug culture we have is killing America," Manchin said.
