Chief Justice John Marshall administered the first executive oath of office ever taken in the new federal city in the new Senate Chamber (now the Old Supreme Court Chamber) of the partially built Capitol building. The outcome of the election of 1800 had been in doubt until late February because Thomas Jefferson and Aaron Burr, the two leading candidates, each had received 73 electoral votes. Consequently, the House of Representatives met in a special session to resolve the impasse, pursuant to the terms spelled out in the Constitution. After 30 hours of debate and balloting, Mr. Jefferson emerged as the President and Mr. Burr the Vice President. President John Adams, who had run unsuccessfully for a second term, left Washington on the day of the inauguration without attending the ceremony.
