Donald Trump has used a press conference at his North Korea summit in Vietnam to accuse Michael Cohen of lying “almost 95 per cent” in his testimony to congress.

The Hanoi summit intended to address North Korea’s nuclear ambitions was cut short on Thursday afternoon after the Trump administration and Kim Jong-un failed to reach an agreement.

In a hastily convened news conference by the White House, the US president was asked what he thought of Cohen’s evidence to the House oversight committee on Wednesday, in which he branded his former boss a “racist, conman, and cheat“.

“I tried to watch as much as I could, I wasn’t able to watch too much because I’ve been a little bit busy,” Mr Trump said. “But I think having a fake hearing like that and having it in the middle of this very important summit is a terrible thing. They could have made it two days later or next week and it would have been even better, they would have had more time. But having during this very important summit is incredible.”

Mr Trump next wrongly claimed Cohen had told lawmakers there had been no collusion between the Trump campaign and Russia. Mr Cohen in fact said he had no “direct evidence” bu that, “I have my suspicions”.

The biggest revelations from Cohen's testimony Trump did not provide evidence for why he avoided the Vietnam draft Having long said that he was not drafted to Vietnam due to a medical issue, Cohen claimed that Trump could not provide evidence of this. “Mr Trump claimed it was because of a bone spur, but when I asked for medical records, he gave me none and said there was no surgery," Cohen told the hearing, he also stated that “he told me not to answer the specific questions by reporters but rather offer simply the fact that he received a medical deferment" Sky

Mr Trump said: “He lied a lot, but it was very interesting, because he didn’t lie about one thing. He said ‘No collusion with the Russian hoax’, and I said, ‘I wonder why he didn’t lie about that too like he did about everything else’.

“He lied about so many things. I was actually impressed that he didn’t say, ‘Well I think there was collusion for this reason or that’. He didn’t say that. He said, ‘No collusion’, and I was a little impressed by that frankly, he could have gone all out. He went about 95 per cent instead of 100 per cent.

“But the fact is is there is no collusion and I call it the witch hunt. This should never happen to another president, this is so bad for our country, so bad, and you look at this whole hoax, I call it the Russian witch hunt, I now add the word ‘hoax’.”

He concluded: “The most important question up there was the one on collusion and he said he saw no collusion. So we’ll see what happens, but it was pretty shameful I think.”

Cohen’s explosive public testimony on Wednesday, in which he presented evidence Mr Trump was aware of illegal hush money payments and that he personally reimbursed his former fixer, will be followed on Thursday by a behind closed doors grilling by a congressional panel investigating Russia’s interference in the 2016 election.
