The White House will campaign for Clinton, but not in the SOTU speech.

...The Brady Handgun Violence Prevention Act (Pub.L. 103–159, 107 Stat. 1536, enacted November 30, 1993), often referred to as the Brady Act and commonly called the Brady Bill,[1][2] is an Act of the United States Congress that mandated federal background checks on firearm purchasers in the United States, and imposed a five-day waiting period on purchases, until the NICS system was implemented in 1998.

It's true that Sanders voted against the bill and I won't waste time explaining why since no one cares. I will point out that the bill went through five iterations and the sole reason for Sanders NAY vote remained intact throughout the process. Also, every other measure besides that single provision is something that Senator Sanders has supported over his career.
