The Oath of Office will be Administered to President-elect Barack H. Obamaby the Chief Justice of the United States The Honorable John G. Roberts, Jr.

10.6%George Washington is the only U.S. President to date whose Inauguration Day swearing-in was administered by someone other than the Chief Justice (in both 1789 and 1793). That's 3.5% of the 57 Inauguration Days to date.For the nine Presidents who assumed office mid-term due to the death or resignation of the preceding President, only four of them had the oath administered by the Chief Justice, either initially or as a follow-up; 55.6% did not.
Neither the first Chief Justice, John Jay, nor the nominal second Chief Justice, John Rutledge, administered the Oath of Office to any US President. The practice wasn't established until the third Chief Justice, Oliver Ellsworth, participated in John Adams' 1796 inauguration.The incumbent Chief Justice, John G. Roberts, Jr., who has only been in office since 2005, has only sworn in one President, Barack Obama, because the United States has had only a single Presidential election during Roberts' tenure.
Aint nobody got time fo dat!!
Chief Justice of the United States Supreme Court, John Roberts
He took the oath of office on March 14, 1861 for the first time administered by then Supreme Court Chief Justice Robert B. Taney who was Chief Justice from March 28, 1836 till October 12, 1864.
The majority of the 43 men who became president were sworn in by the chief justice, but at least seven presidents were not. According to Wikipedia, "from 1789 through 2013, the swearing-in has been administered by 15 Chief Justices, one Associate Justice, three federal judges, two New York state judges, and one notary public." In fact, it is customary rather than mandatory for the chief justice to give the oath-- among the presidents not sworn in by the chief justice were George Washington, Calvin Coolidge, and Lyndon Johnson. (Johnson was the only president sworn in by a woman-- Sarah T. Hughes, a district court judge.)
Chief Justice John Roberts administered the oath to Obama for the second time.
