Mitt Romney announced his selection of U.S. Rep. Paul Ryan of Wisconsin as his running mate for the White House on Saturday, a move that has charged both parties. In front of the USS Wisconsin docked in Norfolk, Va. Romney introduced the 42-year-old congressman as a person who will help lead the country “to widespread and shared prosperity.”

Leading up to Saturday’s announcement there was increasing conversation among press and pundits over Ryan’s potential for the Romney ticket.

On Friday at 11:06 p.m., Romney communications director Gail Gitcho tweeted, “.@MittRomney will announce his VP pick tomorrow in Norfolk. Download the VP app to be the first to know. http://mi.tt/Mitt-VP  #Mitt2012.” Shortly thereafter, an press release to reporters trumpeting: “MITT ROMNEY ANNOUNCES VICE PRESIDENTIAL CANDIDATE IN NORFOLK SATURDAY.” ABC’s Jonathan Karl reported that other frontrunners – Ohio Sen. Rob Portman, former Minnesota Gov. Pawlenty and Florida Sen. Marco Rubio – had been told they were not the pick. Near early dawn, the Romney app officially announced Ryan as the running mate.
