It was a made-for-TV moment that all presidents would relish, but it seemed especially significant for the man who turned a reality TV career into a successful bid for the presidency.
Donald Trump triumphantly greeted the three Americans released by North Korea in the early morning darkness at Joint Base Andrews outside Washington early Thursday, an image one can expect to see over and over again come the 2020 U.S. presidential election campaign.
“It was a very important thing to all of us to be able to get these three great people out,” Trump told reporters on the tarmac. He then went on to speculate that live television coverage of the arrival “probably broke the all-time in history television rating for 3 o’clock in the morning.”
It was a moment the president gladly seized given that his White House has been buffeted by a chaotic mix of policy and personal drama in recent days. The prospect of a potentially historic breakthrough on North Korea could move a number of other unwelcome distractions to the side, including the ongoing Russia investigation, the growing legal difficulties for Trump’s personal lawyer, Michael Cohen, and the soap opera that the Stormy Daniels story has become. Daniels is the adult film actress who claims she once had an affair with Trump. He denies the claim.
Trump also announced Thursday on Twitter that he will meet with North Korean leader Kim Jong Un on June 12 in Singapore. A new CNN poll found that 77 percent of those surveyed support Trump meeting the North Korean leader, and 53 percent approve of his handling of the North Korea issue generally.
Those numbers are in keeping with a general trend of late that has seen the president’s poll ratings improving, perhaps in part because of the strong economy.
