New article of impeachment needed

It is a constitutional right and duty of the House of Representatives to conduct impeachment proceedings if the House decides there is a reason to do so. It is the constitutional duty of the Senate to vote to remove or keep in place the impeached President.

I think it is unconstitutional for the target of an impeachment investigation to refuse to allow witnesses to respond to subpoenas issued by the House. Apparently this lawless president has just declared nobody will be allowed to respond to House subpoenas.  

This seems to me to be an impeachable offense in itself. This should now be the first article of impeachment.  Obstruction of justice. Obstruction of Congress. 

Congress cannot allow this. Congress is equal to the president. 

Trump continues his march toward autocratic rule. He must be stopped.
