1st presidential debate between Trump and Biden spirals into chaotic clash

ABC News Chief Anchor George Stephanopoulos called Tuesday's debate the worst he has ever seen in his life. 

"I have to speak personally here, as somebody who's watched presidential debates for 40 years, as somebody who's moderated presidential debates, as someone who's prepared candidates for presidential debates, and someone who's covered presidential debates, that was the worst presidential debate I have ever seen in my life -- a lot more heat than light over some 90 minutes," he said.

ABC News Chief White House Correspondent Jonathan Karl said, "It looked as if both men lost this debate" but added that it was Trump who had more to lose. 

"In that sense the real loser is Donald Trump," Karl added. "Donald Trump was the one that needed to change the dynamic of this race."

ABC News' Senior Congressional Correspondent Mary Bruce reported that the Biden's campaign is "feeling very good right now," following the debate, saying they believe every time Biden "went around the president" and spoke directly to the viewers "they were winning."

TRUMP'S STATEMENT: "Every year, I get the call, 'California's burning. California's burning.' If that was cleaned, if you have forest management, good forest management, you wouldn't be getting those calls."

FACT CHECK: Trump's repeated comments connecting forest management and wildfires ignores the increasing impact on climate change on how quickly the fires develop and spread. 

Trump has focused on forest management when talking about wildfires in western states, often criticizing local leaders who have disagreed with his response to climate change. 

While decisions about how to manage forests and wildfires are important, Trump's stance disregards evidence that climate change is playing a significant role in why wildfires have become so destructive in recent years. 

During a briefing on wildfires in California earlier this month Trump refuted State Secretary for Natural Resources Wade Crawfoot when he described the impact of increasing heat and drought on the conditions that lead to fires. Trump said, "It'll start getting cooler," directly contradicting conclusions by climate scientists who argue temperatures around the world will continue to rise by saying, "I don't think science knows actually."  

Increasing heat and droughts are "supercharging" wildfires by creating drier conditions for trees and brush. Warmer temperatures have also decreased moisture from melting snow and allowed bark beetles to travel further north, killing millions of trees, according to the National Climate Assessment published in 2018. 

These factors allow fires to spread more quickly. 

As the planet continues to warm, those conditions will only get worse, making wildfires more dangerous, climate scientists say.

The majority of land impacted by wildfires in states like California, Washington and Oregon is also managed by the federal government, which proactively removes dead trees and brush and conducts controlled burns to keep forests healthy.

BIDEN'S STATEMENT: "He (Trump) has executive orders that have no power. He hasn't lowered drug costs for anybody."

FACT CHECK: Trump signed an executive order in September aimed at lowering drug costs by trying to reduce the prices Medicare pays for prescription drugs, but experts have said it is unclear what authority the president has to carry it out.

His orders, if enacted, would lower drug prices by directing drugmakers to offer their medicines to Medicare at the same prices they do in other countries. However, the process is likely to take months, and court challenges should be expected.

Trump has promised several versions of this idea for nearly two years, and Department of Health and Human Services has never proposed rules for how this would work. 

Also, in an analysis released earlier this month, GoodRx found drug prices are surging faster than any other medical service or good, increasing by 33% since 2014.
