By Erica Werner Associated Press WASHINGTON - Congress' approval rating hovers around 15 percent, but there's one group of people excited about the institution: the newly elected lawmakers who are about to join its ranks. The House will welcome 58 freshmen this coming week, including 43 Republicans and 15 Democrats, pushing the GOP majority to 246 members, the most since the Great Depression. In the Senate, 13 new lawmakers, all but one of them Republican, will be sworn in, flipping control of the chamber to the GOP with a 54-vote majority.
