The Florida man suspected of carrying out a mail bombing campaign against top Democrats and other prominent figures has been charged with five federal crimes, according to court documents.
The man was identified by law enforcement officials as Cesar Sayoc, 56, of Aventura, Florida. Kamala Harris, D-Calif.; and James Clapper, the former director of national intelligence who has criticized President Donald Trump.
Fox News contributor Rochelle Ritchie said Friday that she reported such a tweet by the suspect earlier this month - only to be told by Twitter that "there was no violation of the Twitter Rules against abusive behavior".
Public records show that Mr Sayoc has been arrested numerous times over the years, including one case in which he was accused of threatening to use a bomb.
Geoffrey Berman, US attorney for Southern District of NY, called Sayoc's conduct "cowardly and reprehensible and totally anathema to our democracy".
All of Sayoc's targets have been critical of President Trump, and all have been the subjects of the president's ire.
In video of the scene, a blue tarp is seen being draped over a large white van believed to belong to Sayoc, who was arrested in an auto parts store.
Trump was briefed on the arrest by chief of staff John Kelly, a White House official said, and the President was planning to make remarks early Friday afternoon.
Press Secretary Sarah Sanders defends President Trump's criticism of the media
Sanders defended the president by saying he has condemned violence in all forms since day one and will continue to do so. Even as the White House was fighting back against criticism from the left, Mr.
His brushes with the law include arrests on charges of felony theft, drug offenses and fraud. It was found at a New York City postal facility and was similar to the other packages, the official added.
In his remarks after the arrest, as in his comments throughout the week, Trump did not mention that the package recipients were all Democrats or officials in Obama's administration, in addition to CNN, a news network he criticizes nearly daily.
The first of the bombs surfaced on Monday at the Westchester County, New York, home of billionaire Democratic donor George Soros. While the FBI's lab is still working to determine if the devices were functional, Wray said, they did contain "energetic material" - meaning the right combination of heat, shock or friction could have set them off.
Mr Clapper described the mail bomb scare as "definitely domestic terrorism".
The development came amid a coast-to-coast manhunt for the person responsible for a series of explosive devices addressed to Democrats including former President Barack Obama, former Vice-President Joe Biden and Hillary Clinton.
None of the bombs exploded, but FBI Director Chris Wray said Friday, "These are not hoax devices". However, the address for Holder was incorrect, and Wasserman-Schultz's office in Sunrise was the return address.
On Wednesday, the Secret Service announced that they stopped two bombs in the process of being sent to Hillary Clinton and former President Obama.
Tensions are running high ahead of the November 6 elections that could shift the balance of power in Congress, which is now controlled by Trump's fellow Republicans.
The van had numerous stickers showing President Donald Trump and Vice President Mike Pence, as well as a "CNN SUCKS" sign, according to a screenshot posted on Twitter by a CNN reporter.
