For historical reference, let me point out that I can't recall a veto that has been overridden ever here, and both bills that were vetoed had enough votes to override if they had kept their whip count together. Wonder why, but it may be the authority of the Presidency carries a lot.
The Senate overrode the veto of the None of the Above (and possibly Below) Act as well as the Clean Energy Act. To my knowledge, this is the first bill to remain off the books after a veto, though I'm not too sure about that.
Marijuana.
And one of my education bills, but we got another one passed and not vetoed.
