Citing his alarmingly unconstitutional behavior, Coulter cited his disregard of the Obamacare law, disregard of immigration law and disregard of the drug laws as three main reasons he should be impeached. He has no role in writing legislation. Hes vetoing legislation by refusing to enforce it. This is the bottom of the slippery slope, she said. I think he would be impeached if he werent Americas first black president.
