Care to point it out then?Actually, collusion is legal as long as it doesn't lead to an act that is illegal. However that may be, two years of investigations has not produce a single piece of evidence to prove there was any collusion between the Trump campaign and the Russian government.
The real investigation (Mueller's - forget about Little Devin's clown show) has been going for only ten months. You have no clue what evidence there is, but obstruction of justice is one that it would take a complete idiot not to see.
