U.S. President Donald Trump is continuing to take political shots on foreign soil even as he prepares for a high-stakes meeting with North Korean leader Kim Jong Un.
Trump is tweeting during downtime at his hotel in Hanoi that he has now "spent more time in Vietnam than Da Nang Dick Blumenthal."
Trump was referring to Connecticut Sen. Richard Blumenthal, who served in the Marine Corps Reserves during the Vietnam War and apologized in 2010 for saying he had served in Vietnam.
Trump adds that Blumenthal's "war stories of his heroism in Vietnam were a total fraud."
Blumenthal is a Trump critic and has brushed off Trump's attacks in the past, tweeting in 2017 that Trump's "bullying hasn't worked."
Trump also is tweeting that he talked about the incident in his meetings with Vietnam's leaders Wednesday. That would be a highly unusual topic of conversation for an American president on the world stage.
