“Social Security and Medicare are under renewed threat from Tea Party extremists in Congress,” reports the Alliance for Retired Americans. They’re co-sponsoring a rally Thursday at the Capitol that’s expected to draw thousands to join Senator Harry Reid, Senator Elizabeth Warren, other members of the House and Senate, the Koch Sisters, seniors from across the country, advocates for seniors, union members and other concerned Americans to tell the GOP “Hands Off Social Security and Medicare!” The 1:30p rally is in Upper Senate Park. “We’ll send the message that we need to protect Social Security and Medicare from benefit cuts, privatization and vouchers,” says ARA.
