FORT BEND COUNTY, Texas -- The owner of the truck with the controversial "F__k Trump" sticker added a new one over the weekend: "F__k Troy Nehls."

Karen Fonseca and her family are making it clear they aren't backing down.

Along with her attorney and family, Fonseca held a press conference outside the Fort Bend County Justice Center Monday morning "regarding the injustice against" her by "Fort Bend County Sheriff Troy E. Nehls."

Her attorney said they are considering filing civil rights lawsuit against the sheriff.

Her supporters say they are "fighting to protect her against the political target placed on her for simply exercising her First Amendment Right to Free Speech in opposition to President Trump!"

Fonseca's daughters also spoke at Monday's press conference.

“You haven't been with my mom for 18 years.That's my hero right there. She's everything,” Fonseca’s daughter said after her family received backlash last week.

"No matter what race, religion, or belief you may have, we are all equal. Not any one of us is any better than anyone else. Everyone's voice should be heard. And I'm just one person," mom Karen Fonseca said at the press conference.

"What are we teaching our next generation of presidents to be?... If you can say ‘grab those women by the p****,’” Fonseca said, referencing President Trump. "He says it and nobody deletes it.”

Fonseca originally made headlines after Nehls threatened to arrest her for the anti-Trump sticker on her pickup.

She said Monday, however, the sheriff's Facebook post only strengthened her case.

"He actually put us out there and more recognized than it ever has been before. And to me, it's been coming back as a positive for going ahead standing up and not backing down," said Fonseca.

But Fonseca was also joined by State Ron Reynolds, who demanded an apology from Nehls for “making her family’s life a nightmare."

On Nov. 15, Nehls posted a photo of Fonseca's truck on Facebook with the caption: "I have received numerous calls regarding the offensive display on this truck as it is often seen along FM 359. If you know who owns this truck or it is yours, I would like to discuss it with you," the post read. "Our Prosecutor has informed us she would accept Disorderly Conduct charges regarding it, but I feel we could come to an agreement regarding a modification to it."

After the story went viral and thousands of commenters defended the sticker as free speech, Nehls deleted the post.

Fonseca was arrested shortly after for an outstanding warrant from 2014.
