WASHINGTON (AP) — Congress is back to work on Monday, facing a hefty list of unfinished business and a politically driven agenda in an election year. The Senate has scheduled votes on President Barack Obama's nomination of Janet Yellen to head the Federal Reserve and a three-month extension of benefits for the long-term unemployed. If confirmed, Yellen would be the first woman to serve as chairman of the Federal Reserve. Democrats are focused on extending the benefits for an estimated 1.3 million Americans. The payments stopped on Dec. 28. Republicans see a political boost in the troubled implementation of Obama's health care law. The GOP-led House has scheduled a vote this week on legislation dealing with security of personal data. All 435 House seats and 35 Senate seats are up in November.
