CLEVELAND - Today is day two at the Republican National Convention and the day Donald Trump's official nomination process begins. 

Trump received a rousing ovation as he surprised the convention on Monday night when he offered a brief introduction for his wife, Melania.  

Melania spoke about her husband's dedication to the country.

Monday's official theme was "Make America Safe Again," and former New York City Mayor Rudolph Giuliani put terrorists on notice.

The night also featured speeches from Republican lawmakers like former Texas Gov. Rick Perry, as well as former sitcom stars and reality TV favorites.  

Current law enforcement officials had their turn, as well as veterans, and Pat Smith, whose son Sean was killed during the 2012 attack on the U.S. consulate in Libya.  

Hillary Clinton was the secretary of state when that attack occurred, and Smith says it's a key reason she's supporting Trump.

Day two of the convention will feature several speakers talking about job creation. The official theme is, "Make America Work Again."  

The slate of speakers includes UFC President Dana White, House Speaker Paul Ryan, and Donald Trump Jr.
