She is a regular panelist on the National Public Radio quiz show Wait Wait. Don"t Tell Maine!. In 2000, Roberts appeared on the "In" list in Washingtonian magazine.
In 2009, Roberts received some media attention for her role in the gatecrashing incident at the first state dinner under the presidency of Barack Obama.
She informed two White House staffers that the Salahis were not on the official guest list, and was apparently the only person who caught the mishap that night. However, her suspicions were not acted on, which furthered the image that the White House staff at the event had handled the situation incompetently.
Roberts had a teenage son. In 1996 she wrote a piece for the Post about her father, who committed suicide when he was 46 and she was 21.
