McMaster struggles to clean up mess made by Trump’s London tweets at White House briefing

Donald Trump's national security adviser, Lt. Gen. H.R. McMaster, tried to explain Friday why the president had claimed Scotland Yard had London terrorists "in their sights."

“Another attack in London by a loser terrorist,” Trump tweeted early Friday morning. “These are sick and demented people who were in the sights of Scotland Yard. Must be proactive!”

United Kingdom Prime Minister Theresa May scolded Trump over the tweets, telling the president he shouldn't speculate about terror attacks.

McMaster insisted that Trump wasn't speculating. "I think if there was a terrorist attack here, god forbid, that we would say they are in the sights of the FBI. So I think he didn't mean anything beyond that."

"I'm sorry, I'm not clear," a reporter replied. "He was saying generally terrorists are a focus of Scotland Yard or what he saying in this specific incident Scotland Yard knew they were coming?"

"I think he means generally," McMaster replied.
