No, the link to the tweet itself was fine. I don't care what anyone has to say about the tweet. Having just looked at the LaRouche PAC website, seems clear they support Lyndon LaRouche, didn't find any explicit support to any particular candidates, Trump or anyone else.
While it's clear she's a member of the PAC and they've claimed responsibility, her being a Trump supporter seems as unclear as the LaRouche PAC supporting Trump. Seems they are a policy based PAC, with news and opinion.
I would think they would be an organization you could get behind, they want to see a revival of NASA and increased space exploration.
