TAMPA, Fla. -- Ron Paul's appearance Tuesday on the floor of the Republican National Convention evoked split conventions of the past as the retiring Texas congressman received a hero's welcome from supporters.

The former two-time GOP presidential candidate walked out to greet a roaring group of supporters from the Nevada delegation, one of several he won during the detailed process of allocating delegates to this convention.

When asked by NBC News what he hoped to accomplish by visiting the floor, Paul said, "Just saying hi to some friends from Nevada."

Paul supporters started chanted, "Let Him Speak!" When Romney supporters started chanting "Romney, Romney!" Paul backers screamed "Ron Paul! Ron Paul," drowning out the delegates pledged to the Republican nominee-in-waiting.

After posing for pictures and signing some autographs, Paul left the floor ahead of the official start of the session. The convention will feature a video tribute to Paul, and his son, Kentucky Sen. Rand Paul, will address delegates this week.
