Trump signs 'seriously flawed' Russia sanctions bill

US President Donald Trump has signed what he called a "seriously flawed" bill imposing new sanctions on Russia, pressured by his Republican Party not to move on his own towards a warmer relationship with Moscow in light of Russian actions.

The legislation is aimed at punishing Moscow for interfering in the 2016 US presidential election and for its military aggression in Ukraine and Syria, where the Kremlin has backed President Bashar Assad.
