Moscow (CNN) Outspoken Russian Senator Alexey Pushkov claimed Friday on Twitter that US President Donald Trump and senior figures in his administration are not on the same page on Russia. The tweets from Pushkov, chairman of the Information Policy Committee in Russia's upper house of parliament, came a day after US Secretary of Defense James Mattis and US Secretary of State Rex Tillerson commented on Russia while attending summits in Europe. Pushkov tweeted early Friday: "Trump hopes to make a deal with Russia. Mattis thinks (in vain) that he can put pressure 'from a position of strength'. Tillerson is playing a 2nd Kerry. Three lines from 1 administration."
