Law enforcement across the U.S. should "pay attention" to former President Trump's calls for his supporters to protest in the event of his arrest this week, Sen. Mark Kelly, D-Ariz., said Sunday.

Kelly stated that Trump's supporters have a First Amendment right to peacefully protest, but he argued that police should be prepared to ensure that demonstrations don't turn violent. Trump claimed on Saturday that New York authorities may be planning to arrest him this week following an indictment related to his relationship with adult film star Stormy Daniels.

"The [former] president's supporters, they have First Amendment rights, and they should be able to exercise those peacefully," Kelly said during a Sunday appearance on CNN. "I think it's gonna be important for law enforcement to pay attention to, you know, protests and make sure it doesn't rise to the level of violence."

Trump urged his supporters to "protest" and "take our nation back" in messages many have compared to his statements prior to the pro-Trump storming of the U.S. Capitol on January 6.

Democrats on Capitol Hill blasted Trump for a Saturday morning social media post that urged his supporters to take action if he is arrested.

"NOW ILLEGAL LEAKS FROM A CORRUPT & HIGHLY POLITICAL MANHATTAN DISTRICT ATTORNEYS OFFICE, WHICH HAS ALLOWED NEW RECORDS TO BE SET IN VIOLENT CRIME & WHOSE LEADER IS FUNDED BY GEORGE SOROS, INDICATE THAT, WITH NO CRIME BEING ABLE TO BE PROVEN, & BASED ON AN OLD & FULLY DEBUNKED (BY NUMEROUS OTHER PROSECUTORS!) FAIRYTALE, THE FAR & AWAY LEADING REPUBLICAN CANDIDATE & FORMER PRESIDENT OF THE UNITED STATES OF AMERICA, WILL BE ARRESTED ON TUESDAY OF NEXT WEEK. PROTEST, TAKE OUR NATION BACK!, [sic]" Trump posed to his Truth Social account.

Former House Speaker Nancy Pelosi, D-Calif., was among to first to attack Trump on Saturday.

"The former president's announcement this morning is reckless: doing so to keep himself in the news & to foment unrest among his supporters," Pelosi tweeted. "He cannot hide from his violations of the law, disrespect for our elections and incitements to violence. Rightfully, our legal system will decide how to hold him accountable."

Democratic Leader Rep. Hakeem Jeffries of New York echoed Pelosi, arguing Trump was attempting to "fan the flames" of violence.

"We live in a democracy," wrote Jeffries. "Right-wing extremists who fan the flames of political violence with inflammatory rhetoric are not fit to serve. American values over autocracy."

A bill making its way through Florida’s legislature would ban elementary school discussions on sexually transmitted diseases and sexual education topics such as menstrual cycles.

The legislation, sponsored by Republican state Rep. Stan McClain, passed the House Education Quality Subcommittee on Wednesday by a 13-5 vote. 

McClain has said the bill will make sex ed classes across the state’s public school systems more uniform and give parents more of a platform to speak out about curricula they do not approve. 

The bill would ban discussions in elementary school classrooms on topics such as STDs, and require schools to teach that a person’s sexual identity is determined biologically at birth. Under the bill, sex ed classes would be restricted to sixth grade through high school. 

Democrats in the state have criticized the bill over it banning discussions on menstrual cycles for girls younger than sixth grade. The average age girls first get their period is age 12, with the range of age stretching from 10 to 15 years old.

"So if little girls experience their menstrual cycle in fifth grade or fourth grade, will that prohibit conversations from them since they are in the grade lower than sixth grade?" Democratic state Rep. Ashley Gantt asked McClain last week.

"It would," McClain responded.

McClain said the intent of the bill is not to punish teachers who speak with young girls about their periods, and is "amenable" to making some changes to the bill.

The bill would require school materials to be approved by the Florida Department of Education, and would establish objection forms to the school community that would include contact information for school district leaders, WUSF reported.

If an objection is filed regarding pornography or "sexual conduct," the bill would require such materials to be pulled within five school days "and remain unavailable until the objection is resolved."

Gantt decried the bill as one that encourages book banning, WUSF reported.

"I hope that we all understand that we are taking away the ability for our children to be critical thinkers, by telling them we want to protect their innocence. They’re going to be adults one day, and they need to be informed adults," Gantt said last week.
