Long gave other examples - increased heart attacks because of stress, people falling off their house trying to fix the roof or dying in auto crashes in intersections where the lights aren't working.
In a tweet on Thursday in reference to emergency responses to Hurricane Florence, President Trump claimed that the relief of Hurricane Maria in Puerto Rico was "An incredible success", despite a death count of almost 3,000 individuals.
The president reiterated the claim days later, insisting that the death toll had risen "like magic", after he had initially been told in the immediate aftermath of the hurricane that the storm had caused "anywhere from six to 18 deaths".
"The bottom line is, we push forward on that authority as much as we can", he said on CBS' "Face the Nation".
"Spousal abuse goes through the roof". "They should be ashamed of themselves and they should be apologizing to the American public and the people of Puerto Rico who have had to go through this now again, the number of deaths without again, evidence, without death certificates, without burials, without any factual basis for an analysis of what is Puerto Rico's, one of its greatest tragedies in its history".
Talking about the figures coming from unrelated sources, Long said, "The George Washington study looked at what happened six months after the fact".
The president has drawn criticism as he has asserted without evidence in recent days that the death toll from a hurricane past year in Puerto Rico was inflated to make him look bad.
According to the Post, Long, in explaining the president's point, "suggested researchers took into account deaths due to a range of causes with tenuous links to the storm, such as automobile accidents and domestic violence".
Ocasio-Cortez, a 28-year-old Democrat expected to become the youngest woman ever elected to Congress on November 6, tweeted: "My own grandfather died in the aftermath of the storm".
She said her grandfather was in a medical facility in Puerto Rico and "passed away in the middle of the night" after the storm. "The people who pass away in these storms are the most vulnerable". They are our elderly.
As the fallout from Trump's comments on Hurricane Maria continues, questions also have swirled around Long after reports that he is under investigation for his use of government vehicles.
"I've never been asked to resign", Long said, maintaining that he speaks with Nielsen "every day" and that the two have a "very professional, functional relationship".
Long on Sunday denied any misconduct.
