Republicans on the House Oversight and Government Reform Committee are demanding access to Obama administration documents that were used to brief Congress and the Trump and Clinton campaigns about Russian interference in the 2016 election.

Rep. Jim Jordan of Ohio, the top Republican on the committee, and Rep. Mark Meadows of North Carolina, said they want the information as part of their ongoing effort to investigate "the federal government's actions in advance of the 2016 election."

In a letter to Department of Homeland Security Secretary Kirstjen Nielsen, the two Republicans said DHS had brief Congress about Russia's efforts to interfere with the election. They said the Obama administration in that briefing "assured Members that it was adequately addressing any attempted interference in the election."

Republicans along with President Trump have charged that the Obama administration downplayed the possibility of Russian interference until Trump won the election, and that the Russia threat has been overblown in order to delegitimize the president.

Jordan and Meadows asked for all documents used to brief lawmakers and campaign officials in 2016, and all communications between Obama administration officials on the Russian threat. They asked for the documents to be delivered by March 19.

The GOP request came just a day after House Democrats launched a wave of their own document requests to the Trump administration. The House Judiciary Committee asked for detailed documents of 81 people or entities linked to the White House, and letters were sent out by four Democrat-led committees on Monday asking for details of Trump's conversations with Russian President Vladimir Putin.
