Parliament to 2002 during the 37th Parliament. From 2001 to 2009, Kenny was the first chair of the Senate committee on national security and defence. In 2009, Kenny gained national spotlight with a YouTube video of the Senate Defence Committee where several heated arguments occurred in committee when the meeting was disrupted repetitively by senators choosing not to follow rules. He is also a member of the Trilateral Commission. In October 2013, CBC News reported that a former staffer of Kenny's had accused him of sexual harassment. Kenny withdrew from the Liberal caucus on November 21, 2013 pending the outcome of an investigation into the allegations. In April 2014 an independent investigator cleared Kenny on all three charges brought forward by his former employee.

At the end of January 2018, Kenny wrote the Speaker of the Senate to inform him that he would retire on February 2, 2018, ten months before his mandatory retirement date of December 2018, citing his ill health. The decision was made a day after Kenny's former staffer who had accused him of sexual harassment emailed Prime Minister Justin Trudeau asking him to re-open the investigation so it could hear from the other
