Lara Trump, co-chair of the Republican National Committee and daughter-in-law of former President Donald Trump, appeared saddened but proud when recalling the "frightening" assassination attempt Saturday against her father-in-law at a campaign rally in Butler, Pa.

“There is no doubt that Saturday was one of the most frightening moments of my father-in-law’s life,” Lara Trump told the audience at Tuesday night's Republican National Convention. “Millimeters separated him from life and certain death. And yet, it was in the midst of it all, as he was jostled off stage by Secret Service, that he knew how defining that moment would be for our country, and he hoisted his fist in the air.”

The crowd erupted into chants of “fight, fight, fight!”

The assassination attempt on Trump, and a general belief among Republicans that a win for their candidate in November will refortify national security, dominated the topics discussed during the later portion of the Republican National Convention’s second night, themed “Make America Safe Again,” in Milwaukee, Wis.

Lara Trump, who is married to the GOP presidential nominee's son, Eric Trump, wrapped up convention night Tuesday as the keynote speaker.

“Last Saturday was a jarring reminder that we as Americans must always remember: there is more that unites us than divides us,” she said. “We all want this country to be great, even if we don't always agree on the best way of doing that. And with every bone in my body, I can tell you that all Donald Trump wants to do, and has ever wanted to do, is make this country great again for all of us.”

She referenced Trump’s presidential record of tax cuts, energy independence, unemployment rates, prison reform, border security, peace agreements in the Middle East, and the creation of the U.S. Space Force as proof that a second Trump administration would benefit American peace and prosperity.

Florida U.S. Sen. Marco Rubio, who was on the shortlist for Trump’s vice-presidential candidate picks, spoke just before Lara Trump Tuesday night, and argued there is nothing divisive about Trump’s America-first agenda, and nothing dangerous about Trump’s supporters, as Democrats maintain.

“What they ask for is not hateful or extreme,” Rubio said of Trump's supporters. “What they want is good jobs and lower prices. They want borders that are secure, and for those who come here to do so legally. They want to be safe from criminals and from terrorists. And they want our leaders to care more about our problems here at home than about the problems of other countries far away.”

Dr. Ben Carson, the 17th U.S. Secretary of Housing and Urban Development under the Trump administration, talked briefly as well, noting how the assassination attempt put the stakes of the election into perspective.

“These events brought unusual clarity to the times we are living in. We have all harbored the nagging feeling that everything we love is slipping away,” said Carson. “This is a man who is a gift to us as a nation.”

The night concluded with speakers calling for unity, for votes, and for grit.

“We must stand up, and we must fight,” Rubio said. “Fight not with violence or destruction, but with our voices and our votes. Fight not against each other, but for the hopes and dreams we share in common and make us one. And fight for an America where we are safe from those who seek to harm us on our streets, and from abroad.”

The sloped roof where a would-be assassin took aim at former President Donald Trump during a campaign rally in western Pennsylvania wasn’t safe enough for snipers.

This is a reason for not posting someone there, U.S. Secret Service Director Kim Cheatle said in an interview with ABC News on Tuesday.

“That building, in particular, has a sloped roof at its highest point,” she said. “And so, you know, there’s a safety factor that would be considered there that we wouldn’t want to put somebody up on a sloped roof.”

“And so, you know, the decision was made to secure the building, from inside,” Cheatle added.

The comment comes three days after 20-year-old Thomas Crooks opened fire on a crowd in Butler, Pa., less than 15 minutes after Trump took the stage, striking him in the ear. Trump was wounded but has continued his schedule, arriving in Milwaukee, Wis., on Sunday for the Republican National Convention and appearing in the main arena Monday night.

Since then, authorities – namely the Secret Service – have faced tough questions about the apparent security lapses that allowed the gunman to scale the roof 147 yards from the stage at the Butler Farm Show Grounds.

Eyewitnesses can be seen on video shouting for police to intervene as they watched Crooks belly crawl into position. Law enforcement was also stationed inside the building.

In a separate report from NBC News, a local official said a Butler Township police officer was boosted to the roof of the building, where he grabbed onto a ledge and saw Crooks, who then turned his rifle toward the officer. Unable to grab his weapon or radio, the officer dropped eight feet to the ground, injuring his ankle.

(The Center Square) – Western Wisconsin’s congressman says he was assaulted at Milwaukee’s Republican National Convention, but a women’s group disagrees.

Republican Congressman Derrick Van Orden took social media Tuesday to say a protester with the group Code Pink assaulted him while he was standing in line at the RNC.

“While standing in line to enter an event at the RNC today, I was assaulted by what appeared to be a member of the pro-Hamas group CODEPINK. A nearby police officer witnessed this assault and I understand they have been arrested,” Van Orden said. “This appears to be an incident of political violence and I will never tolerate this. Regardless of the severity of the violence, political violence is political violence.”

Code Pink almost immediately said Van Orden was the one who bumped into who they called a “visibly Palestinian” woman.

“CODEPINK's Palestine Organizer Nour [Jaghama] has been unjustly arrested at the RNC after a congressman shoved past her and had her arrested on false charges of ‘assault,’” Code Pink said in a tweet of its own.

Milwaukee Police questioned Jaghama, then were later seen taking her away.

The department says the incident is “under investigation.”

Van Orden said the incident is just the latest example of violence from the Left.

“Republicans have been intimidated and targeted for years, including the attempted assassination of President Trump and we will no longer standby and allow lawlessness,” he said. “There is no place for political violence in this country and I have repeatedly called for people who choose this path to be prosecuted to the greatest extent of the law.”

The Milwaukee County District Attorney’s Office said Tuesday that charges in the case are “under review.”

Van Orden was in line for an event at the Pfister Hotel at the time. It’s not clear if the Code Pink protester was going to the same event or was just standing in line.

Van Orden has been a target for protesters. He is in the middle of a race for his second term in Congress for Wisconsin’s Third Congressional District. He has a history of confrontations. It was July of last year when Van Orden was accused of yelling at a group of Capitol Hill interns who were taking pictures and videos inside the Capitol Rotunda.

He defended his actions by saying the Capitol Dome is hallowed-ground, and needs to be treated with respect.
