Trump news: President lashes out at ‘nation of terror’ Iran over oil tanker attacks and questions ex-adviser’s Mueller evidence

Donald Trump has insisted that Iran is responsible for an attack on two oil tankers in the Strait of Hormuz, after the Pentagon released night-vision footage of what it says is an Iranian navy boat retrieving an unexploded mine from the hull of one of the targets.

Phoning in to Fox and Friends for an interview on his 73rd birthday, the president said: ”Iran did do it. You know they did it because you saw the boat.”

Meanwhile in an ABC interview, Mr Trump questioned the testimony given to the Mueller investigation by ex-White House counsel Don McGahn, saying the adviser “may have been confused” when he said under oath that his former employer instructed him to fire the special counsel.

He also said Friday that "of course" he would go to the FBI or the attorney general if a foreign power offered him dirt about an opponent.

It was an apparent walk back from his earlier comments that he might not contact law enforcement in such a situation.

Mr Trump, in an interview Friday with "Fox & Friends," said he would look at the information in order to determine whether or not it was "incorrect."

But he added that, "of course you give it to the FBI or report it to the attorney general or somebody like that."

Earlier in the week, Mr Trump had told ABC News that he would consider accepting information from an outside nation and might not contact law enforcement.

His assertion that he would be open to accepting a foreign power's help in his 2020 campaign had ricocheted through Washington, with Democrats condemning it as a call for further election interference and Republicans struggling to defend his comments.
