Conspiracy is a secret plan by a group to do something unlawful or harmful. Collusion is secret-cooperation in order to deceive others.
Example of conspiracy: You and a guy conspire to knock off a bank, he picks out a getaway car while you seek costumes to disguise yourselves.
Example of collusion: You know someone is going to knock over a bank, possibly buy you a car with proceeds, do nothing about it ... you have colluded, and if that someone is hiding out across the street and a police officer is about to knock on that door, but you offer him a cup of coffee, possibly allowing someone to get away, you are obstructing justice.
The Russians interfered with our elections, folks, and that isn’t cool, but it is a fact. So why isn’t our president indicted for looking the other way?
It is a fair question. Director of the FBI Robert Mueller, a Marine combat veteran and lifelong Republican, had two powers given to him by the Justice Department – exonerate (no conspiracy, no collusion and no obstruction of justice) or no exoneration. He chose no exoneration of the president. Again, he didn’t have the power to indict a sitting president. No exoneration was the most powerful indictment of the president’s actions he could enforce.
President Trump colluded with the Russians and obstructed American justice.
