On the Sunday morning talk shows, three sitting lawmakers and one former Republican politician all pushed back, in varying degrees, against President Donald Trump's claim that he is being vindicated in the Russia investigation. Special counsel Robert Mueller's indictments on Friday of Russians for meddling in the 2016 US election made it clear the interference was designed to boost Trump and undermine Democratic nominee Hillary Clinton's chances in the presidential race. Sen. James Lankford, Rep. Adam Schiff, Sen. Bernie Sanders, former New Jersey Governor Chris Christie, former director of national intelligence James Clapper, and radio host Rush Limbaugh all offered their thoughts on Sunday.
