He has also been arrested for theft and domestic violence.
According to the records, he is a registered Republican with a lengthy criminal past - including once making a bomb threat - and a history of posting inflammatory broadsides on social media against Trump's political foes.
Television images from Plantation showed investigators using a blue tarp to cover a white van, which was plastered with political decals and stickers including several of Trump, before removing it on a truck.
His white van, which was seized by authorities, had numerous signs in the windows showing Trump, including a drawing depicting the president standing on top of a tank emblazoned with "Trump" on the sides.
Federal Bureau of Investigation agents arrested Sayoc at an AutoZone parking lot in Plantation, Florida, about six miles west of Fort Lauderdale, Friday morning as he was nearing his white van, which has been covered with images political in nature, including images of notable liberals such as Hillary Clinton and former President Barack Obama. Federal authorities took Cesar Sayoc into custody on October 26, 2018, and confiscated his van, which appears to be the same one.
Debra Gureghian, general manager of a restaurant in Fort Lauderdale, said Sayoc dressed impeccably during his stint as a delivery driver.
"I've seen the guy maybe 80 times and I never said a word to him because I had a feeling he was a little off".
"I could really tone it up, because the media ... has been unbelievably unfair to Republicans and certainly to me", Trump said Friday.
"He was very angry and angry at the world, at blacks, Jews, gays", she said. She says Twitter got back to her within 24 hours and said the tweet did not violate their rules against abusive behavior. "He was very, very unusual".
The company did eventually suspend Sayoc's account, but it wasn't until after he'd been arrested.
Marc Weiss saw Sayoc almost every morning at 6 a.m. for the last four or five months.
It is a retweet of a composite image claiming that Andrew Gillum, the Democratic candidate for governor of Florida, "admitted" taking money from billionaire George Soros. Officials were uncertain whether the devices were poorly designed or never meant to cause physical harm. Cory Booker was found in Florida, while another found in NY was addressed to former U.S. Director of National Intelligence James Clapper.
In a June post, Sayoc wishes a happy birthday to Trump.
"Thank you for your recent report". That was not uncommon for the amateur body builder and former stripper whose social media accounts are peppered with memes supporting Trump and posts vilifying Democrats.
Sayoc describes himself on one of his Twitter feeds as a former professional soccer player, wrestler and cage fighter.
In 1980, he spent three semesters as a student at Brevard College in North Carolina, a university spokeswoman told BBC News. "And respect all living things". Unconquered Seminole Tribe will answer your threats.
"We have no evidence that any of our offices have been targeted, but we are in close contact with the authorities as this situation develops", said the statement issued by the Gillum campaign.
Sayoc, who was born in NY, was sentenced in August 2002 for threatening to throw a bomb in a conversation with a Florida utility representative, according to Ronald Lowy, a Miami attorney who represented him.
