A Twitter thread from a past friend of the shooter states that the 22-year-old was "never a white nationalist" and "never a leftist." Just "crazy being crazy."
The bipartisan deal on gun regulations making its way through the senate includes more background checks for people under 21, mental health and school safety funding, and state grants for red flag laws.
The shooter lived a troubled life. He had no apparent father figure, his mother suffered from drug abuse, and his grandmother wanted to kick his mother out of the house.
