The point is that a PAC that used to raise money for, and support, Nikki Haley now supports Harris.

This is technically true but doesn't tell the whole story either:

One of those groups, Primary Pivot, is run by Robert Schwartz, a liberal activist who has spent his career countering democratic backsliding in countries across Latin America... “We only care about damaging Donald Trump,” said Schwartz. “For better or for worse, the only thing you can do if you really want to stop Trump is to vote for Haley.”

The explicit goal was to get "Democratic voters to switch their party affiliation to undeclared," and "to persuading already undeclared voters to vote in the Republican primary for Haley."

There's nothng illegal about this or anything.

But to me, the headline is implying that "a pro Haley PAC is now supporting Harris," which is not true. It was never realy pro Haley, it was just anti Trump, and this switch to Harris is not unexpected in the slightest like the headline would lead you to believe. Not like "Conservative PAC now supporting Harris."
