Trump pressure tactics in Comey case ‘chilling’ – but they could backfire, experts say

Former prosecutors condemn takeover of the DoJ' but say chance of success could be tainted by president's comments

Donald Trump's public and private push to have ex-FBI director James Comey indicted on criminal charges is a strong sign of the US slipping into authoritarianism, but it could also taint the case's chances of success because it is evidence of a selective and biased political prosecution, ex-prosecutors and scholars say.

Trump's retribution drive against an old foe he blames for legal and political problems notched a big win when Comey was indicted last week on two criminal counts in Virginia.
