In 2013, I introduced legislation called Grassley-Cruz which targeted felons and fugitives and those with serious mental illness. It directed the Department of Justice to do an audit of federal convictions to make sure felons are in the database. It directed the Department of Justice to prosecute and put in jail felons and fugitives who try to illegally buy firearms.
In the Harry Reid Democrat(ic) Senate, a majority of the Senate voted in favor of Grassley-Cruz, but the Democrats filibustered it. They demanded 60 votes. They defeated it, because they wanted to go after law-abiding citizens instead of stopping the bad guys.
