Former President Trump and four of his rivals for the 2024 Republican presidential nomination will speak Friday and Saturday in Philadelphia at the national gathering of an increasing influential parental rights organization that's stoked controversy.

Trump, the commanding front-runner in the GOP nomination race, will be joined by Florida Gov. Ron DeSantis, former ambassador and former South Carolina Gov. Nikki Haley, former congressman and former Arkansas Gov. Asa Hutchinson, and entrepreneur and political commentator Vivek Ramaswamy in addressing the second annual Moms for Liberty summit.

DeSantis, the first major speaker at the summit on Friday morning, pointed to the protests outside the venue and said "I see that Moms for Liberty is coming under attack by the left, attack by the corporate media, protests out here in the streets. Now you know how I feel everywhere I go. But I want to congratulate you for that because that is a sign we are winning this fight."

And Haley, speaking later on Friday morning, showcased that "I'm a mom, so I can relate to what all these moms are feeling. I mean, we have one job and that's to take care of our families."

The appearances of some of the biggest names among the large field of Republican White House contenders is another sign of the growing clout for the conservative-leaning group, which says it has 285 chapters across 45 states.

"I think it says that parents are a very important part of the future of America and that the candidates care about the issues that parents care about, and they want to make sure that we know that," Moms for Liberty co-founder Tiffany Justice told Fox News Digital on Thursday during the first day of the confab, which the group calls the Joyous Warriors National Summit.
