The third day of the Republican National Convention kicked off Wednesday with Republicans — led by the newly nominated Donald Trump and his running mate, U.S. Sen. JD Vance of Ohio — shifting their focus to issues of national security and foreign policy.

Republicans are expected to focus on Democratic President Joe Biden’s handling of the ongoing crises in Europe and the Middle East. Former Trump administration officials are also expected to take the stage to outline what foreign policy would look like if he returns to the White House for a second term.
