President Donald Trump signed a bill imposing new sanctions on Russia Wednesday morning, putting to rest questions about whether he would support the legislation passed by Congress last week while excoriating the measure as "significantly flawed." The bill sanctions Russia — citing its cyberhacking as well as aggression in Ukraine and Syria — while also slapping new sanctions on North Korea and Iran. But the legislation also makes it harder for the president to lift these sanctions unilaterally, requiring permission from Congress before waiving them. Trump signed the bill behind closed doors, with no press coverage.
