The issue is simple. Congress -- meaning both houses acting together legislatively -- can fashion and enforce a cutoff of funds for the previously approved border wall if that is what Congress votes for and it can secure the President's acquiescence or over-ride his veto. Unless and until that occurs though, the President may reallocate funds to build the wall by relying on other provisions of appropriations law.

In the current case, there is no action by Congress. Since the House acting alone cannot change the law, the House lacks the standing to appear in court and speak as if it has the authority of the entire Congress for its position. Therefore, the President may legally reallocate funds and build the wall -- and Nancy Pelosi and the House Democrats leave with nothing.

For all the talk of the controversy as being between the President and Congress, it is really only between the House and the President, with the GOP controlled Senate on the President's side.

The House can act constitutionally and impeach, the Senate may not agree.... that’s the way the game is played.
You’d think the House knows the rules as laid out in the Constitution. Then again....
