Clinton, who formally ended her presidential bid two weeks ago, is set to return to the Senate Tuesday - the first time in over 17 months the New York Democrat will set foot in the chamber not being a candidate for president. Put another way, the last time Clinton was not a presidential candidate, in January 2007, oil was trading at just over $50 per barrel.
Watch: How are the Clintons doing?
Clinton spokesman Philippe Reines confirms Clinton will be back to work on the Hill Tuesday and Wednesday, though he would not give further details on the senator's schedule for those two days.
Clinton is also set to address the National Association of Latino Elected Officials in Washington on Thursday before joining up with former rival Barack Obama on the campaign trail Friday.
According to the Obama campaign, the two candidates will travel to Unity, New Hampshire - a small town on the state's western border where both candidates received 107 votes in the January primary, according to the campaign.
Clinton's first public appearance since ending her presidential bid came Sunday at a high school graduation ceremony in New York City. There she told the group of students running for president was a "extraordinary experience."
"I have just finished the most extraordinary experience that anybody could possibly have: being able to travel around our country, this great, sprawling, diverse country from one end to the other, meeting thousands and thousands of people who want a better life for themselves and their families, who believe in all their heart in the American Dream," she told graduates of Pelham Prep Academy."
