Well, there is nothing in the Constitution to stop the House of Reps from impeaching the President, Vice P, Judges, other Officers for whatever the House wants.
But, as a practical matter, and it is unfortunate, it takes a minimum of felonious conduct to get our reps to even think about booting a President. Usurpation of Constitutional powers should be the standard, not felonies.
I would add that the Framers gave us this power because it was a corrective to the abuse we took as colonists. We could not stroll into the House of Commons and file Articles of impeachment for removal of the King of England. Instead, we were left with the options of doing nothing or revolting.
We HAD the power, as in past tense, to impeach the President to peacefully remove a despot. Unlike other countries, we are not supposed to storm the White House and do nasty things to the President and his czars. The Framers gave us a peaceful means to be rid of scoundrels and oppressors.
There is no question that Hussein does not conduct himself as if he could be booted from power. It is just the opposite; he does what he wishes, craps on our beloved Constitution with absolutely no fear of removal from office.

The Congress has the power to subpoena birth documents and passport records. They refuse to do so.
It just sets my teeth on edge. I am doing all in my power within our local Tea Parties to see that these people are not re-elected.
Only a valid president can be impeached. A usurper would be arrested.
Congress doesn't need to go through impeachment. All they need to do is issue a few subpoenas, but, they **refuse** to do what is just and right.
