A federal panel reviewing President Donald Trump's White House ballroom has set April 2 for a final vote on the project. Will Scharf, chairman of the National Capital Planning Commission, made the announcement at the start of the panel's meeting Thursday in Washington. The panel had been expected to vote Thursday on the project, but Scharf said the vote was moved to next month to give everyone who wants to offer public comment a chance to do so. More than 100 people had signed up to comment at Thursday's meeting. Scharf said that would probably extend into Friday.
