Not only the President. Federal judges, Cabinet Secretaries, and Senators all have been impeached in the past. The actual line from the Constitution is: "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 Misdemeanors." While it may not be a good idea to impeach Obama over this, they could impeach Clapper over it, as he is the one who petitioned the government to dismiss the case on the basis that the plaintiffs didn't have grounds as they could not demonstrate that they had been affected, or possibly against Solicitor General Donald Verrilli who made the argument in court. Coupled with his lies to Congress during hearings about whether the NSA collected data on Americans ("not wittingly"), Clapper would probably be the best target.
