Censor.NET reports citing several senators' statements.
"The President's extended signing statement, however, demonstrates that Congress is going to need to keep a sharp eye on this Administration's implementation of this critical law and any actions it takes with respect to Ukraine," Senator Chuck Schumer wrote on Facebook. " This legislation shows its possible for the two parties to work together to rein in the President when he veers off track, and I hope it serves as a model for the future."
Schumer wrote it was a good thing to do for Trump: " The President signing the legislation into law today, although begrudgingly, was the right thing to do. It's a critical response to Putin's brazen attack on the cornerstone of our democracy - our elections."
Sen. John McCain wrote on Facebook: " The concerns expressed in the President's signing statement are hardly surprising, though misplaced. The Framers of our Constitution made the Congress and the President coequal branches of government. This bill has already proven the wisdom of that choice."
House Democratoic Whip Steny Hoyer posted on Facebook: | President Trump had no choice but to sign our bipartisan Russia sanctions bill into law, given the veto-proof majorities with which it passed the House and Senate. Americans from across the political spectrum are deeply concerned - and rightly so - about Russia's interference in our election and its aggression in Ukraine. Our sanctions bill will ensure that this President cannot take action unilaterally to benefit Russia without any change in its behavior."
