Wildfires have been sweeping across California at a magnitude the United States hasn’t seen in over a decade, according to The New York Times, which reported that this summer has been a record-breaking fire season, with 820,000 acres already consumed in California alone. Similar wildfires are sweeping the state of Washington, as well.

Despite evidence of climate change and its connection to these kinds of extreme events, President Donald Trump falsely claimed in a tweet on August 5 that “bad enviornmental laws” and limited access to water were making the fires worse.

Experts widely believe the president conflated two unrelated issues. There’s long been a conflict in California between farmers and environmental groups over how much water should go to crops versus to rivers and lakes — but that fight doesn’t have any effect on firefighting. (According to a post by the official California Department of Corrections and Rehabilitation Twitter account, 2,000 inmates are fighting those fires, including 58 “youth offenders” who are paid roughly one dollar an hour for this dangerous work.)

"The issues over the allocation of water between environmental and agricultural interests have nothing to do with firefighting,” Keith Gilless, UC Berkeley professor of forest economics and chairman of the California Board of Forestry and Fire Protection, told Politifact. “And I’m not aware of any situation in which those conflicts have restricted the availability of water for firefighting purposes."

This false claim is just one of many the White House has made this summer. According to The Washington Post, by August 1, Trump had made 4,229 false or misleading statements in office. His daily average for false and misleading claims has increased throughout the presidency, from roughly five claims a day during his first three months in the White House to an overall daily average of almost eight per day by August. And in June and July, according to the Post, Trump had an average of 16 claims a day.

When the White House itself is a primary source of misinformation, it can skew the public’s perception of the nation as a whole. So we paired with PolitiFact to do some fact-checking. Here are some of the greatest inaccuracies put forth by Trump this summer:

1. Trump falsely claimed that U.S. Immigration and Customs Enforcement “liberated towns” from MS-13 gangs, although there’s no evidence that such gangs ever controlled towns to begin with.

On June 30, Trump tweeted: “I have watched ICE liberate towns from the grasp of MS-13 & clean out the toughest of situations. They are great!"

PolitiFact reported that neither the White House nor ICE has presented any evidence of towns under the control of MS-13, a violent gang founded in Los Angeles in the 1980s, by refugees from civil wars in El Salvador, Guatemala, and Honduras who lived together in low-income neighborhoods.

This tweet wasn’t an isolated incident. During a July rally in Florida, Trump falsely claimed that gangs including MS-13 are “occupying our country like another nation would." Experts agree there is no evidence to support such a claim, PolitiFact reported.

"MS-13 in certain cities have made inroads, in certain neighborhoods and schools, but to say entire towns have been under MS-13 control, that simply has never been substantiated," Fulton T. Armstrong, a research fellow at the Center for Latin American and Latino Studies at American University, told PolitiFact. "In the absence of any evidence, one would have to say it's either a gross exaggeration if not a fabrication, because we've never known that."
