President Trump is threatening to veto legislation reauthorizing expired government surveillance tools if it passes in the House, citing “massive abuse” of the government powers in the Russia investigation.

“If the FISA Bill is passed tonight on the House floor, I will quickly VETO it. Our Country has just suffered through the greatest political crime in its history. The massive abuse of FISA was a big part of it!” Trump tweeted Wednesday, referring to the Foreign Intelligence Surveillance Act.
