CLEVELAND >> Republicans criticism cast Donald Trump as the right man for turbulent times as they opened their presidential convention Monday against a backdrop of unsettling summer violence and deep discontent within their own party.
For Trump, the convention was also an opportunity to assure party leaders and voters alike that there's a kinder gentler side to what many see as merely a brash businessman. Trump's family is playing a starring role, beginning Monday night with an evening speech by his wife, Melania Trump, who has kept a low profile throughout the campaign.
In an unusual step for a candidate, Trump announced he would come to Cleveland and go onstage on opening night to introduce her.
Ahead of Trump's arrival, tumult broke out on the convention floor after party officials adopted rules by a shouted voice vote, a move aimed at blunting anti-Trump forces seeking to derail his nomination. Delegates erupted in competing chants in a televised dispute Republican leaders had hoped to avoid.
"I have no idea what's going on right now. This is surreal," said Utah Sen. Mike Lee, who had helped lead the efforts to force a state-by-state roll call vote on the rules.
Trump hoped the chaos would be little more than a footnote in the four-day convention. Despite persistent party divisions, his campaign is confident Republicans will come together behind their shared disdain for Hillary Clinton.
Convention speakers planned to relentlessly paint the presumptive Democratic nominee as entrenched in a system that fails to keep Americans safe.
"Hillary Clinton cannot be trusted. Her judgment and character are not suited to be sitting in the most powerful office in the world," said Sen. Joni Ernst, R-Iowa, according to excerpts of her speech released in advanced.
The convention comes amid a wrenching period of violence and unrest, both in the United States and around the world. On the eve of the opening, three police officers were killed in Baton Rouge, Louisiana, the city where a black man was killed by police two weeks ago.
Republican National Committee Chairman Reince Priebus welcomed delegates with a brief acknowledgement of the "troubling times" swirling outside. The chairman called for a moment of silence out of respect for "genuine heroes" in law enforcement.
In a matter of weeks, Americans have seen deadly police shootings, a shocking ambush of police in Texas and escalating racial tensions, not to mention a failed coup in Turkey and gruesome Bastille Day attack in Nice, France.
Trump has seized on the instability, casting recent events as a direct result of failed leadership by President Barack Obama and by Clinton, who spent four years in the administration as secretary of state. But Trump has been vague about how he would put the nation on a different course, offering virtually no details of his policy prescriptions despite repeated vows to be tough.
Campaign chairman Paul Manafort said Trump would "eventually" outline policy specifics but not at the convention.
Clinton, during remarks Monday at the NAACP's annual convention, said there was no justification for directing violence at law enforcement.
"As president, I will bring the full weight of the law to bear in making sure those who kill police officers are brought to justice," she said.
Clinton was a frequent target of the eclectic group of lawmakers, military service members and entertainers headlining opening night of the convention. They include Ernst of Iowa and Jeff Sessions of Alabama, immigration advocates and a woman whose son was killed in the Benghazi attack that occurred during Clinton's tenure at the State Department.
"I blame Hillary Clinton personally for the death of my son," Pat Smith said in an emotional speech. "If Hilary Clinton can't give us the truth, why should we give her the presidency."
Also taking the stage were actor Scott Baio and Willie Robertson, star of Duck Dynasty, who took the stage with an American flag bandanna wrapped around his head.
"No matter who you are, Donald Trump will have your back," Robertson said as he opened the evening program.
The line-up of speakers and no-shows for the four-night convention was a visual representation of Trump's struggles to unify Republicans. From the party's former presidents to the host state governor, many leaders were staying away from the convention stage, or Cleveland altogether, wary of being linked to a man whose proposals and temperament have sparked an identity crisis within the GOP.
Trump's team insists that by the end of the week, Republicans will plunge into the general election campaign united in their mission to defeat Clinton. But campaign officials undermined their own effort Monday by picking a fight with Ohio Gov. John Kasich, who is not attending the convention and has yet to endorse Trump.
Manafort, in remarks to reporters at a Bloomberg breakfast, called Kasich "petulant" and said the governor was "embarrassing" his party in his home state.
Even some of those participating in the convention seemed to be avoiding their party's nominee. When House Speaker Paul Ryan spoke to Wisconsin delegates Monday morning, he made no mention of Trump in his remarks.
Ryan, asked at a later event whether Trump was really a conservative, said: "Define conservative; he's not my kind of conservative."
