I still don't believe this amounts to collusion, since at this point there's no evidence information was exchanged, anything was offered for it, and that plans were devised from the meeting. There is one thing I don't buy, however......
"[The President] said he has had no meetings, was aware of no meetings with Russians, was not aware of this one until really right before it all broke," [Sekulow] said.
The last part is implausible, IMO. To think his son didn't run to him with this right away doesn't seem credible, given how this family operates.
