Senate Democrats allege Trump administration has buried 1,400+ climate studies

Details: Sen. Debbie Stabenow (D-Mich.) released a list of over 1,400 climate studies by Department of Agriculture researchers, many of which warn of the potential effects of climate change on the public and on the agriculture sector, specifically. The agency released the studies after Politico reported in June that the USDA had purposefully buried its own researchers' findings.

• Research included in the Democrats' report lays out the potentially harmful effects of climate change on crop production. The issue is increasingly important for farmers throughout the Midwest who have suffered from extreme weather's toll on harvests.

What they're saying: Stabenow said it is "outrageous" that "critical information for communities, for farmers, for those of us who care deeply about what’s happening to agriculture, these are not being shared with the people who need to know."

The other side: A USDA spokesperson said allegations of the department suppressing findings are false.

• "We have repeatedly provided the Senate Agriculture Committee with evidence to the contrary, and the department has been transparent and communicative to the committee in response to their questions on research," the spokesperson said.
• The spokesperson added that "the list of studies linked in the report were provided by the USDA to the committee and are all publicly available."

Between the lines: Climate change has become an increasingly prominent issue in the Democratic Party, with 2020 candidates partaking in climate-focused town halls and forums and releasing trillion-dollar plans to tackle the issue.

• "After nearly a month of stonewalling, it appears clear that the President has chosen the path of defiance, obstruction, and cover-up," the letter reads.

The state of play: Several White House officials have told Axios' Alayna Treene that the administration has no plans of complying with the committees' demands for interviews or documents without a full House vote formally approving an impeachment inquiry.

The big picture: The Trump administration's initial refusal to turn over the whistleblower complaint on the president's interactions with Ukraine is what led House Speaker Nancy Pelosi to finally support a formal impeachment inquiry.

• Johnson asked the Justice Department earlier this week to look into links between Ukraine and Hillary Clinton's 2016 presidential campaign. His letter questioned the narrative that Biden's actions in Ukraine had nothing to do with his son's connection.
• However, it was also discovered that he signed onto a 2016 letter that mirrored Biden's work to reform Ukraine's prosecutor general and judiciary.
• There is no evidence that Biden's reform work in Ukraine was to protect his son's business dealings, as the president and some of his allies allege, or that he committed any form of corruption.

The state of play: Sondland, a Trump political appointee who donated $1 million to the president's inaugural committee, denied that there was a quid pro quo between the Trump administration and Ukraine's government in a series of text messages that former Ukraine special envoy Kurt Volker provided to a group of House committees investigating the Trump-Ukraine matter.

• "I think it’s crazy to withhold security assistance for help with a political campaign," Bill Taylor, the top U.S. diplomat to Ukraine, texted Sondland.
• Sondland texted back: "Bill, I believe you are incorrect about President Trump's intentions. The President has been crystal clear no quid pro quo's of any kind."
• The New York Times reported that Sondland's response came only after he spoke to the president.
