Donald Trump Jr. took to Twitter on Thursday morning to defend his father in the wake of former FBI Director James Comey’s bombshell testimony.

Reacting to Comey’s descriptions of how President Donald Trump asked him to drop the FBI’s investigation into former National Security Adviser Michael Flynn, Trump Jr. called Comey’s account “B.S.” and said that if Trump had really wanted Comey to shut down the investigation, he would have issued a direct order.

“Flynn stuff is BS in context,” Trump’s eldest son wrote. “2 guys talking about a guy they both know well. I hear ‘I hope nothing happens but you have to do your job.’ Very far from any kind of coercion or influence and certainly not obstruction! Knowing my father for 39 years when he “orders or tells” you to do something there is no ambiguity, you will know exactly what he means.”

Trump Jr. then mocked Comey for admitting that if he were a “stronger guy,” he would have been more assertive in telling President Trump that it was wrong to ask him to drop the Flynn investigation.
