In Washington, where pressing the flesh is just part of doing business, lawmakers have been given strict guidelines regarding the Pope's upcoming visit -- to keep their hands to themselves. Party leaders sent lawmakers the protocol advisory on Friday ---- no handshakes or long conversations with the pontiff -before his speech to congress. While no specific mention was made prohibiting them from kissing the pope's ring, they've been reminded that Pope Francis is on a very tight schedule. On Thursday, Pope Francis will enter the House chamber through the same door the president Barack Obama uses for his State of the Union address, wading through a sea of lawmakers to reach the podium. This visit is the Pope's first to the U.S. since become head of the Roman Catholic Church.
