Someone get Trump to the next school shooting in time to test this:
At the meeting, Mr. Trump slammed reports that deputies who were on the scene of the shooting did not enter Marjory Stoneman Douglas High School.
"I really believe I'd run in there even if I didn't have a weapon," the president said.

I could be wrong, but didn’t Cory Booker actually go into a burning house to rescue a woman?
Huh, yes.
yup
and Trump is credited (kindof) for breaking up a mugging, a long time ago
