The Washington Post reports:

President Trump said Sunday that he would demand that the Justice Department explore whether it or the FBI “infiltrated or surveilled the Trump Campaign for Political Purposes” — escalating a battle over federal law enforcement’s use of a confidential source to aid its probe into whether the Trump campaign and Russia coordinated to influence the 2016 election.

Trump wrote on Twitter, “I hereby demand, and will do so officially tomorrow, that the Department of Justice look into whether or not the FBI/DOJ infiltrated or surveilled the Trump Campaign for Political Purposes – and if any such demands or requests were made by people within the Obama Administration!”

The tweet seemed to be a response to recent reports about the FBI using a longtime intelligence asset to advance its investigation into Russian election meddling. Trump and his allies have seized on the use of the asset to claim that the FBI has spied on his campaign.
