Trump’s July 4 speech was roughly 40 minutes long.

Context

The coverage says he finished “after roughly 40 minutes,” and notes that he sometimes speaks for twice as long.

Timing

He took the stage at 11:15 p.m., about 1 hour and 15 minutes later than planned after weather delays.

Why it mattered

The address was part of the “Salute to America 250” Independence Day event in Washington, DC, marking the 250th anniversary of U.S. independence.

TL;DR: about 40 minutes.
