New York Governor Andrew Cuomo says that Mr Trump and politicians across American need to think about their rhetoric in the wake of the intercepted mail bombs.
"If we don't stop this political mania, this fervor, rancor, hatred, you'll see this again and again and again," Mr Cuomo told MSNBC. "We have to get to the genesis, and the genesis is an overheated, vitriolic political division in this country and it starts with the leaders, and it starts with the president."

Here is Mr Trump speaking about the arrest
Officials are investigating a suspicious package intercepted in Burlingame, California, that was addressed to billionaire and Democratic donor Tom Steyer, according to CNN.
Security has been heightened at federal facilities around the country in the wake of the suspicious packages, Homeland Security Secretary Kirstjen Nielsen said Friday at a news conference in Calexico, California.
Mr Sayoc's Twitter account appears to be mostly pro-Trump content, including what looks like a video of him chanting the president's name at an indoor rally.
To recap: the 11th and 12th suspicious packages were sent this morning to Democrat Senator Cory Booker and former Director of National Intelligence James Clapper, found in Miami, Florida, and near the CNN offices in New York, respectively.
Within hours, Mr Sayoc was arrested in Florida.
Read more about what happened this morning here:
Fifty-six-year-old Mr Sayoc was arrested at the car parts shop Autozone in Plantation, Florida.
A van spotted outside of the store, before being taken away by federal investigators. It was adorned with several stickers of Republican politicians in support of Mr Trump and one that says "CNN sucks,"
"I can do the greatest things for our country and on the networks...it will show badly," Mr Trump just said, continuing his criticism of the media as there were a few "fake news" shouts from the crowd.
Mr Trump said these "despicable acts" have no place in the US, but critics have panned the president for not addressing his own negative rhetoric - particularly at recent political rallies - and it's possible role in these attacks.
On Wednesday evening, just hours after the Secret Service intercepted an explosive device package sent to Hillary Clinton, the president chanted "lock her up" at rally in Wisconsin.
This morning he once again hit out at CNN:
He sneaks in a quiet "thank you" to the media and said "congratulations to all law enforcement" for the capture of the suspect, who is now arriving at a FBI facility in Florida.
Several of the packages were addressed from Florida, specifically House Democrat Debbie Wasserman Schultz - though her name had been spelled incorrectly on the return address labels.
Mr Trump just finished a briefing with the US Department and praised the "FBI...and all law enforcement throughout the entire country".
"They worked so hard...and done it so quickly, it's like a needle in a haystack," the president said.
"We must show the world we are united together...there is no country like our country. Every day we are showing the country just how truly great we are".
Donald Trump, speaking at a black youth leadership summit, announced the suspect's arrest to cheers from the crowd.
He said he had "instructed" federal law enforcement to spare no expense in finding the culprit and promised "swift justice"
President Donald Trump, who has repeatedly bashed the news media, has pushed back against CNN for "blaming" him for the pipe bombs that have been sent to his political rivals this week.
The president lamented and complained that he is held to a different standard than his critics because he is the leader of the United States.
“Funny how lowly rated CNN, and others, can criticize me at will, even blaming me for the current spate of Bombs and ridiculously comparing this to September 11th and the Oklahoma City bombing,” Mr Trump tweeted just after 3am Friday. “Yet when I criticize them they go wild and scream, ‘it’s just not Presidential!’”
The suspect's name has been made public. Cesar Sayoc Jr has been arrested in Plantation, Florida.
One emerging theme — though perhaps ultimately inconsequential — is that whoever has been sending these pipe bombs has struggled to spell the names of the intended recipients correctly.
The sender or senders misspelled former CIA Director John Brennan's name incorrectly ("Brenan"), for instance, and has misspelled Florida Representative Debbie Wasserman Schultz's name incorrectly as well ("Shultz").
In addition to the misspelled names, it is worth noting that Mr Brennan is a contributor for NBC and MSNBC in Rockefeller Centre — but his package was sent to CNN's office in the Time Warner Centre.
