Bernie Sanders has been calling on Joe Manchin to support President Joe Biden’s full agenda for weeks. On Friday night, Manchin signaled he’s had enough of that.

In response to an op-ed from Sanders (I-Vt.) published in Manchin’s hometown paper on Friday night, Manchin snapped back: “This isn’t the first time an out-of-stater has tried to tell West Virginians what is best for them despite having no relationship to our state.”

“Congress should proceed with caution on any additional spending and I will not vote for a reckless expansion of government programs. No op-ed from a self-declared Independent socialist is going to change that,” Manchin said in a statement on Friday evening shortly after the op-ed published. Sanders caucuses with Democrats but is still technically an independent.
