Democratic National Convention 2012 memorable moments (PHOTOS)

First lady Michelle Obama claps on stage after speaking during day one of the Democratic National Convention at Time Warner Cable Arena on September 4, 2012 in Charlotte, North Carolina.

As the Democratic National Convention in North Carolina prepares for President Barack Obama's speech, here are some memorable moments from the convention so far.

Obama will be accepting his party's nomination Thursday night, in a smaller venue than originally planned, due to severe weather conditions. The president held a conference call this afternoon, apologizing to disappointed attendees who had tickets but would not be able to fit in the Time Warner Cable Arena, saying, "We can't let a little thunder and lightning get us down," according to The Los Angeles Times.
