The American Civil Liberties Union of Texas posted on Facebook that Fonseca's message is protected speech and urged her to reach out to the organization.
Fort Bend County Sheriff Troy Nehls posted a photo of the back of a white pickup truck with a tinted back window and a large sticker that reads, 'F*** Trump and F*** you for voting for him'.
The owner of the truck was soon revealed to be Karen Forsenca, a mother of 12 (!) who adamantly refuses to alter her vehicle. "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".
Nehls later responded to his Facebook post with a photo of the Texas criminal code that outlined potential laws the decal could violate.
"I'm offended that a sheriff in the U.S. would harass an American citizen over political speech", comments Jason.
At the news conference, Nehls said he is hoping to remedy the situation by talking to the truck owner and getting the driver to modify the decal.
"It's just our freedom of speech and we're exercising it", she said.

"Due to the hate messages he has been receiving toward his wife and children, the sheriff will not be commenting on the matter further", spokeswoman Caitilin Espinosa said by email.
Texas penal code describes disorderly conduct as "intentionally or knowingly [using] abusive, indecent, profane, or vulgar language in a public place, and the language by its very utterance tends to incite an immediate breach of peace". "They honk their horn, they give you a thumbs up, there is some negativity because we're in a diversified community, but the plusses outweigh the negativity", said Forsenca.
It's unclear whether or not the Fort Bend County Sheriff's Department will proceed with disorderly conduct charges now that Forsenca and her truck have received national attention.
"I drive it all the time on a daily basis", Forsenca said, adding that she shares the truck with her husband. However, Nehls also specifically cited the "offensive language" on the truck as a cause for concern.
A spokeswoman for the sheriff's office, which covers the county just southwest of Houston, said Thursday that Nehls' post was removed once the pickup driver was identified.
District Attorney John Healey disputed Nehls' suggestion that disorderly conduct charges were appropriate in this case, as did free speech advocates.More news: Rescue efforts end after deadly Iran quake
