The man suspected of sending pipe-bomb packages targeting nationally known Democrats and critics of President Donald Trump also spent time on social media attacking liberal elected officials and other prominent progressives around the country, including Oregon Gov. Kate Brown and Portland Mayor Ted Wheeler.

"Another far liberal left Democrat Gov. Oregon exposed former campaign MGR corruption, fraud scams, money laundering," Cesar Sayoc tweeted Oct. 9.

The post included images from two conservative media organizations that have taken aim at Brown during her re-election campaign.

The first, Oregon Watchdog, had distributed a bingo card listing all the department heads the governor had fired or forced to resign.

The second image came from the nonprofit Project Veritas, which released a video earlier this month in which a former campaign manager for Brown was secretly recorded accusing the governor of mismanaging state agencies.

Chris Pair, a spokesman for Brown, told The Oregonian/OregonLive that her office routinely refers online threats made against the governor to Oregon State Police.

Sayoc's tweet, which makes no direct threat against Brown, was never reported to state police, Pair said.

Brown's office this week also announced that the governor's security detail would begin a review of mail screening procedures in light of the pipe bombs sent to other political offices.

It also appears Sayoc on Aug. 2 tweeted a veiled threat to Wheeler, whom he calls "slime scum," along with a photo of the mayor and his wife.

The menacing message came in response to a tweet made by Wheeler in Spanish about Portland's commitment to remaining a so-called sanctuary city for immigrants, an archived version of the exchange shows.

Eileen Park, a spokeswoman for Wheeler, said the mayor's security team had increased its surveillance of his home and office in the last few days and have not found any suspicious packages.

Sayoc was arrested Friday in Florida on suspicion of sending homemade bombs to at least a dozen Trump critics, including former Presidents Barack Obama and Bill Clinton, actor Robert De Niro and philanthropist George Soros.

Twitter suspend Sayoc's account shortly after his arrest.
