R. Nicholas Burns, a former Bush Administration official and think tanker, bashed Donald Trump's foreign policy speech this week, calling him a "dangerous" man.
Burns is the latest think tank power player to critique Mr. Trump's foreign policy. Several weeks ago, more than 100 Republican foreign policy and national security leaders signed an open letter denouncing Trump.
Burns, who serves on the board of directors of Atlantic Council and the Council on Foreign Relations (CFR), is also a visiting fellow at the Hoover Institution.
Over the past few weeks, Mr. Trump and his team have been cozying up more to think tanks, holding secret meetings with some of them. Earlier this week, Trump was hosted by a conservative think tank in Washington, DC to present his foreign policy address.
