CLEVELAND -- Republicans prosecuted their case against Hillary Clinton on Tuesday on the same night they officially chose Donald Trump as their presidential nominee.

New Jersey Gov. Chris Christie, one of Trump's closest allies and a former federal prosecutor, turned Quicken Loans Arena into a courtroom as he slammed Clinton's character, judgment and trustworthiness while delegates on the floor chanted "Lock her up, lock her up."

"Is she guilty or not guilty?" Christie asked after every charge he laid before the crowd.

The delegates responded with a resounding: "Guilty!"

Michael Mukasey, a former attorney general under George W. Bush, said Clinton lied about her motivations in setting up a private email server while secretary of state and said she had therefore disqualified herself from being president.

"Hillary Clinton is asking the people of this country and the people of the United States to make her the first president in history to take the oath of office after already having violated it," he said.

The message the convention should send to her should be "loud, clear and short: No way, Hillary. No way on Earth."

House Speaker Paul Ryan, who had previously offered a lukewarm endorsement of Trump, said he looked forward to sitting behind him in the House chamber when the GOP nominee delivers the State of the Union address. He said, unlike the GOP, Democrats have settled on a tired nominee for 2016.

"They are offering you a third Obama term, brought to you by another Clinton," Ryan said.

Chris Cox, a National Rifle Association lobbyist said Clinton would stack the Supreme Court with justices who opposed the Second Amendment.

"A Hillary Clinton Supreme Court means your right to own a firearm is gone," Cox told delegates.

The Clinton campaign says the former secretary of state has no plans to abolish the right to own a gun, but has called for universal background checks and stricter control of firearms.

Trump basked in the success of officially becoming the Republican Party's nominee and said he is proud to be the party's choice to battle Clinton in November.

"Together, we have achieved historic results, with the largest vote total in the history of the Republican Party," he told delegates in a live video from Trump Tower. "This is a movement, but we have to go all the way."

Trump's appearance came as his campaign sought to turn around a rocky start to the convention, following a plagiarism scandal that erupted around his wife Melania's convention address on Monday night.

He did not mention the controversy over passages lifted from first lady Michelle Obama's convention speech in 2008, simply saying he and his wife had a great time Monday in Cleveland.

The theme of Tuesday evening was "Make America Work Again," and doubled down on the Trump campaign's effort to slam the Obama administration after Monday's program was dominated by speakers painting a dire picture of national security.

Two of Trump's children, Tiffany and Donald Jr., sought to put a more human face on their father as he tries to broaden his appeal, after adopting a confrontational persona in the Republican primary battle.

Fallout from Melania Trump speech

But the fallout over Melania Trump's address, which featured unattributed excepts from a speech by Michelle Obama, mounted as critics used it to question the campaign's competence and readiness for power and the campaign swatted away the controversy as "absurd."

Donald Trump, who briefly introduced Melania on Monday after emerging onto the stage through a cloud of smoke and blue light, was furious about the embarrassment, two sources said. The campaign, however, signaled that no one would be fired or disciplined over the episode.

Trump's campaign manager Paul Manafort accused the Clinton campaign of jumping on the controversy to attack Melania Trump because she was a threat to the former secretary of state's presidential candidacy.

But senior Clinton campaign communications adviser Karen Finney hit back, saying, "You can't blame everything on us. Some of the mistakes that are made are made by the Trump campaign."

Clinton did not weigh into the controversy but did slam the first night of the Republican convention as similar to the "Wizard of Oz."

"Lots of sound and fury, even a fog machine, but when you pulled back the curtain, it was just Donald Trump with nothing to offer the American people," Clinton said in Las Vegas.

It remained unclear, however, whether the firestorm over the Melania Trump speech will have a lasting impact on voters, especially since her speech was an often touching tribute to her husband and her adoptive United States.

The Trump campaign has been the most unconventional political operation in many decades, and political reversals that would have hobbled any other candidacy have repeatedly blown over with little apparent affect.

Top Republicans sought to put the controversy to rest.

"Whatever happened with the writing was unfortunate," Republican Sen. John Barrasso said. "I don't want all the unity of this convention to be overshadowed by that."

Sen. Marco Rubio said he understood "why it's a big deal in terms of the internal, inside baseball of political coverage."

"But I think for the vast majority of Americans, it doesn't really matter one way or the other," Rubio said.
