Republican presidential front-runner Donald Trump will deliver a major foreign policy address in Washington on Wednesday, as he endeavors to become a more sophisticated candidate in anticipation of a general election battle against former Secretary of State Hillary Clinton.

Trump’s campaign said in a statement that the candidate plans to articulate his views on “many serious foreign policy issues facing [the U.S.] and our allies” in a serious and substantive speech hosted by the Center for the National Interest and the National Interest Magazine.
