I think the money laundering theory is ludicrous to be honest. These screenshots show employees of Four Seasons Landscaping from OTHER states, and their legal political donations. There's nothing illegal about it, and it doesn't even relate to the location in question.

There IS definitely a reason they decided to host their press conference here, and there's definitely a reason for Lewandowski's post about them being people that love this country. I think the crematorium theory makes better sense. It's possible that they have that footage, and can not yet disclose that fact. Because, if they DID have that footage, they would have had to immediately launch an investigation, and said investigation would limit what they're allowed to publicly say. But...holding a presser there could be sending the message without actually saying anything about the investigation.

Back to Lewandowski's post. "They love this country and are American patriots". If they didn't love this country and were not American patriots, it would be easy to destroy alleged footage and tell nobody.
