They can pass any law they want to but of course the President has to sign it.
The normal outrage by the public if the President does not sign a law seems to be a thing of the past though.
Also, the Congress seems to check with the President before passing anything that he does not like. This is called an abrogation of powers. Our Constitution clearly states that the three powers, Executive, Legislative, and Judicial have equal power but it seems that two of the three have given up their powers.
Actually, this has occurred because our Constitutional government has failed. We no longer have Government by the people but Government by the Party. That was never what our democracy was meant to be.
What the means is our so called Representatives are voting as their leader wishes instead of what the people wish.
The House and the Senate are both corrupt!
That is what I thought. But many posters are mad because Obamacare was not de-funded by the current GOP congress. Actually Obamacare law was passed by the congress and signed by the president, all democrats of course.
But the congress can not defund an established laws without the president signing the change of funding. So it gets convoluted.
