The Legislative Branch
The US House of Representatives has exclusive constitutional authority to initiate impeachment proceedings.
US Supreme Court justices may be impeached by the House and removed from office if convicted in a Senate trial, but only for "high crimes and misdemeanors," or other offenses described in Articles I, II and III of the Constitution.
Contrary to popular belief, Supreme Court justices don't serve "for life"; they serve "during good behavior." While this is usually the equivalent of a lifetime commission, the phrase means justices may be impeached for the same reasons the President or other government officials can be removed.
The House of Representatives can impeach the President. The Senate conducts the trial and the Chief Justice of the Supreme Court presides for the President.

The legislative branch has the power to impeach (or to bring charge[s] against) the president. The House of Representatives votes on whether to impeach the president. If the vote is to impeach, there is a trial before the Senate acting like a jury, with the Chief Justice of the US Supreme Court presiding over the matter like a judge at a trial.

The president or the Supreme Court Justice could make laws.
A US president cannot hold two government positions at the same time, nor can any other federal government official. Only one former US President has gone on to serve on the Supreme Court: William Howard Taft was Chief Justice from 1921-1930.
