President Donald Trump began one of the most solemn days on the American calendar the way he starts many other mornings: with a tweet criticizing his Justice Department.

Tuesday marks 17 years since about 3,000 people died in the Sept. 11, 2001, attacks, the deadliest ever on American soil. The first message to come from the president's Twitter account on the somber day was a quote from a Fox Business program deflecting attention away from special counsel Robert Mueller's Russia probe and instead toward the Justice Department and Hillary Clinton.

Only after that tweet did the president share a 9/11 memorial post from the White House director of social media, Dan Scavino, with the messages "NeverForget" and "September11th." He quickly followed that tweet up with two other Fox Business and Fox News quotes meant to criticize his Justice Department.

The White House did not immediately respond to a request to comment on the president's tweets.

The tweets preceded Trump's trip to Shanksville, Pennsylvania, where the president and first lady Melania Trump will attend a memorial for hijacked Flight 93 that crashed there on Sept. 11, 2001. Despite Trump's plans, his morning tweets reinforced a perception that he often does not recognize the gravity of national moments.
