Former senator’s comments echo recent call from Erika Kirk that ‘everyone has responsibility’ to tone down hatred

Politicians should “calm down” and stop approaching one another in “attack mode” amid the US’s climate of political violence, former US senator Joe Manchin said on Sunday.

The West Virginia independent who generally caucused with Senate Democrats echoed similar comments made at a town hall Saturday by Erika Kirk, the widow of conservative political activist Charlie Kirk, who was shot to death in September.
