Menendez Sworn in as US Senator

Once a House heavyweight, New Jersey Democrat Robert Menendez on Wednesday became the U.S. senator with the least seniority and couldn't have been more happy about it.

He found it funny when he was stopped by security personnel when he tried to enter areas of the Capitol marked "for senators only," and he said he was still trying to find his way around the Senate side of the building after spending 13 years in the House.

Menendez, sworn in Wednesday, hopes his newness wears off soon, and he rattled off a list of things he hopes to accomplish before he has to face New Jersey voters this year for the right to hold the seat for the next six years.
