Pete Buttigieg blasts Trump after president excoriates him during press briefing

Trump sarcastically called Buttigieg "a real winner."

Buttigieg, the former South Bend, Indiana Mayor who served as secretary of the Transportation Department under former President Joe Biden, sounded off in a post on social media.

"Despicable. As families grieve, Trump should be leading, not lying. We put safety first, drove down close calls, grew Air Traffic Control, and had zero commercial airline crash fatalities out of millions of flights on our watch," Buttigieg declared in a post on X.

"President Trump now oversees the military and the FAA. One of his first acts was to fire and suspend some of the key personnel who helped keep our skies safe. Time for the President to show actual leadership and explain what he will do to prevent this from happening again," he added.

Buttigieg mounted a presidential bid in 2019, but dropped out the next year and endorsed Biden.

"Pete is exploring all of his options on how he can be helpful and continue to serve," a source familiar with Buttigieg's thinking told Fox News Digital. "He's honored to be mentioned for this, and he's taking a serious look."
