WASHINGTON

President Donald Trump will make a "massive" infrastructure announcement Tuesday, his first full day as president in office, according to the White House.

"We will have a big infrastructure announcement," said White House spokesman Karoline Leavitt during an interview with Fox News.

She said the American people will "be hearing from the leader of the free world"

"This man is already doing more in less than 24 hours than his predecessor did in four years,” she said, but indicated she would not get ahead of the president on details of the announcement.

Trump is expected to deliver remarks in the Roosevelt Room with reporters at 4 p.m. local time (2100GMT), according to the White House.
