More GOP lawmakers embrace vaccine but still aren't calling out misinformation about it

(CNN) Senate Minority Leader Mitch McConnell says he's " perplexed " why so many people in the country still aren't vaccinated .
Buddy Carter, a pharmacist and member of the House GOP Doctors Caucus, said on CNN that fellow Georgia Republican Rep. Marjorie Taylor Greene -- whose Twitter account was recently suspended for vaccine misinformation -- has "every right" to her opinion, even though he disagrees with it.
"The misinformation needs to be straightened out, but at the same time, we can't be dictating to these platforms what is misinformation and what is not misinformation," Carter said.
"It's political malpractice that Republicans have not got on this way, way sooner," said Rep. Diana DeGette, a Colorado Democrat.
The House GOP Doctors Caucus, meanwhile, is holding a press conference on vaccines Thursday alongside Scalise and House GOP Conference Chair Elise Stefanik of New York -- a move designed to give the event more star power.

Rep. Lauren Boebert, a Colorado Republican, has referred to health officials trying to get more people vaccinated "needle Nazis" on Twitter.
Said one GOP lawmaker, who would only speak anonymously of the fringe members in the GOP conference: "They need to make sure they have their facts straight.
And Republicans urging vaccine use have been simultaneously eager to take swipes at Democrats, with the 2022 midterms looming.
At the time, Harris and Biden had said they didn't trust Trump's word alone on a potential vaccine, but they did trust the scientists.
And even the vaccine press conference being hosted by the House GOP Doctors Caucus couldn't help but add another item to its agenda that animates the Republican base: the origins of the coronavirus.
