How do we know that they aren't lying to use that they are lying to them?
Two lies don't make a truth. Not even if you lie about lying. They swore to tell the truth, or to uphold the Constitution. That they aren't even trying to do that, even as political "strategery", more than likely mean they ARE in fact telling the truth.
They don't like guns and don't want "We the People" to have easy access to them.
