Democratic Sen. Tom Harkin will retire from the Senate at the end of his term in January 2015, the Associated Press has reported.
The 73-year-old Harkin told The Associated Press in an interview, "It's just time to step aside," noting that by the time he would finish a sixth term, he would be 81.
The AP noted that Harkin has $2.7 million in his campaign war chest and was planning to attend a fundraising event next month.
