I wanted to let you know about a new petition I created on We the People, a new feature on WhiteHouse.gov, and ask for your support. Will you add your name to mine? If this petition gets 100,000 signatures by October 21, 2014, the White House will review it and respond!
You can view and sign the petition here:
He can not be arrested until he is Impeached. The Constitution isn’t silent about why the president can be removed it states: “The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery, or other high Crimes and Misdemeanour's.”
From this we can see that the only way to remove a president is by impeachment in the House by a majority vote and conviction of treason, bribery, high crimes or misdemeanour's by 2/3 vote of the Senate. The House must start impeachment procedures. This also hints to the fact that the president cannot be arrested until he has been convicted by the Senate.
It would seem conceivable that the Senate’s Sergeant at Arms can then officially arrest and imprison him. He cannot be removed from office until after he is convicted and no sitting president will ever be imprisoned as long as he has the power of the Presidency at his disposal. Logic would then suggest that no sitting president can ever be arrested until he is removed from office.
