I think Sen Sessions said he wasn’t going to endorse during the primaries. That said, he said he agree with Trump on trade and one of his primary aides, who I read was instrumental on Sessions with immigration, just joined the Trump team.
I read that Falwell Jr. endorsed Trump - today I think.
I agree on Sessions not endorsing anyone... and I’m happy with Falwell Jr. — but re: your post, I had not heard that one of his primary aides joined the Trump team. That’s great news because it’s a strong indication of Trump’s seriousness on the issue!
