The Florida man arrested in connection with the investigation into the mailing of more than a dozen bomb-like devices to prominent Democrats, also threatened Sen. Jeff Flake in social media posts.

Flake, a vocal Trump critic who abandoned his 2018 re-election efforts after enduring blistering attacks from President Donald Trump, declined to comment to The Arizona Republic Friday about Cesar Sayoc's social media posts targeting him and his wife.

One threatening message included an aerial photo of Flake's home.

Sayoc, 56, who posted pro-Trump material on social media, faces five federal charges in connection to the sprawling federal inquiry into the mailing of at least 13 improvised explosive devices to Democrats.

Sayoc was taken into custody Friday following a manhunt for those responsible for the mail bombs, sent to Trump critics, including the homes of former Presidents Barack Obama and Bill Clinton, the headquarters of CNN and liberal donors George Soros and Tom Steyer.

Sayoc used a Twitter account under the profile "@hardrockintlent" and posted statements about Flake and his wife, Cheryl.

The account had been suspended by Friday afternoon but The Arizona Republic obtained images of two posts.

An Oct. 1 post included four pictures: an image of a figure walking away from a fiery trailer, a picture of two figures blasting fire from a hose-like device, and a picture of the book title, "The Art of War."

The fourth image was the aerial photo of Flake's Mesa home.

"@JeffFlake very nice house Jeff a lot entrances," the post said. "Arizona we will see you Cheryl and your family soon."

That same day, the account tweeted a post that included a portrait of the senator and his wife with their kids, an image of what appears to be the tarot card representing "death," an image of someone with a red gas can and a car, and a picture of Flake and his wife walking in Washington, D.C., being trailed by reporters.

On that day, Flake made national headlines while in Boston for continuing his call for a thorough investigation into Trump's nominee to the U.S. Supreme Court, Brett Kavanaugh.

Flake had called for the FBI to further investigate decades-old allegations of Kavanaugh by Dr. Christine Blasey Ford.

Sayoc's social media posts about Flake emerged as Flake and other elected officials are on heightened alert, given the bomb-like devices.

Flake confirmed to The Republic on Wednesday that he had been alerted to suspicious activity involving him, but he would not talk publicly about the activity.

Flake said the incident, which occurred last weekend, does not appear related to the mailed devices.
