A Democratic Pennsylvania state representative remains defiant amid criticism for videos he posted of himself confronting anti-abortion activists who were protesting outside a Philadelphia Planned Parenthood.

In response to the videos, the chairman of the Pennsylvania Republican Party called on Brian Sims to apologize and U.S. Sen. Ted Cruz, R-Texas, called him a "hateful, angry" Democrat.

But Sims has dug his heels in further and answered his critics with a tweet declaring, "Bring it, Bible Bullies!"

Abortion-rights opponents have responded by planning a protest at the very abortion clinic where Sims was trying to drive activists away.

In a video shared on his Facebook account on April 18, Sims approached a group of about five protesters he says had been "shaming young girls" in front of the entrance to Planned Parenthood Southeastern Pennsylvania.

A female adult approached Sims and explained that they "are actually just here praying for the babies" before he offered $100 to anyone who can identify the girls within the group.

"A bunch of white people, standing out in front of Planned Parenthood shaming people. There is nothing Christian about what you're doing," Sims said.

Texas Republican Sen. Ted Cruz tore into Sims for the video on Twitter Tuesday.

"Hateful, angry Dem state rep videoed himself offering a $100 bounty for the identities of three teenage girls praying outside Planned Parenthood," Cruz said. "Will Dem Party condemns this abuse?"

Sims returned to the same Planned Parenthood on Thursday and shot another video, which he streamed on Periscope and shared on Twitter.

"I'm once again out in front of Planned Parenthood of Southeastern Pennsylvania," Sims said, adding that the clinic is in his district and that he thinks it is "the most heavily protested" Planned Parenthood in the country.

Sims approaches a woman who appears to be holding a rosary and avoiding the camera. He refers to her as "today's protester" and "an old white lady." For more than seven minutes he proceeds to berate the woman for "shaming people for something that they have a constitutional right to do."

"What you're doing here is disgusting. This is wrong. You have no business being out here," he tells her. He accuses her of being engaged in "a racist act of judgment."

Sims repeatedly encourages people to donate to Planned Parenthood "on behalf of this woman" during the video.

"If you're a white person like I am, we have a lot of catching up to do. We have a lot to apologize for and I'm going to start by apologizing for this woman."

The woman ignores Sims for about the first four minutes before telling him to "get your camera out of my face."

"Push back against Planned Parenthood protestors, PLEASE! They prey on young women, they use white privilege, & shame. They’re racist, classist, bigots who NEED & DESERVE our righteous opposition. Push back, please!" Sims wrote in a tweet along with the video.

"Planned Parenthood protesters are scum! I’ve spent years as a patient escort witnessing firsthand the hate, vitriol, hostility and BLATANT RACISM they spew," he said in another tweet on Thursday.

"Wow," Cruz tweeted in response to the second video. "An elected Dem state rep, a 'College Football Captain,' videos himself (presumably he’s proud of this behavior) harassing, insulting & haranguing an elderly lady who quietly prays for him. In what universe are elected officials supposed to treat their constituents like this?"

"State Rep. Brian Sims’ harassment of a woman’s peaceful and religious exercise of her First Amendment rights is yet another example of a troubling trend of growing extremism and hypocrisy among Democrats," Pennsylvania Republican Party Chairman Val DiGiorgio said in a statement on Monday.

"Having met Rep. Sims, I am surprised at this episode of despicable conduct. Given the nature of his conduct, he owes an apology not just to the woman he harassed, but to the people of Pennsylvania that expect more out of their elected officials."

The anti-abortion rights group Live Action shared Sims' second video in a tweet, calling his action "shameful."

"Bring it, Bible Bullies! You are bigots, sexists, and misogynists and I see right through your fake morals and your broken values," Sims replied.

"Oh we're bringing it," tweeted conservative commentator Matt Walsh, who helped organize an anti-abortion rights rally scheduled to be held at 11 a.m. EDT at the Planned Parenthood Southeastern Pennsylvania.

"The rally at the Planned Parenthood in Philly isn't just about the one jerk harassing pro-lifers at that location," Walsh tweeted. "It's about taking a stand against anyone who tries to intimidate those who exercise their First Amendment rights. And it's about standing for life, most importantly."
