Philadelphia Police Commissioner Danielle Outlaw said last week, "At this particular time we do not have any specific or credible threats to Philadelphia. However, this is a fluid situation."

Jeremy David and Jennifer Ricks, of Austin, Texas, flew to D.C. for the inauguration but drove to Philadelphia to see historical sites.
"We've never been to Philadelphia, but I noticed lots of crowds of officers in this part of the city," Ricks said.
Over the weekend the tri-state area capital cities did not see any problems but the threat goes through the week.
