A lawyer's job is to make a client look innocent, if not to prove it — something President Donald Trump's lawyer, Rudy Giuliani, has been struggling with in recent days.
In a string of interviews, Giuliani has walked back a series of potentially damaging statements where he implied there were tapes of his client discussing plans for a Trump tower in Moscow, that Trump was discussing the Moscow project right up until the election and that he didn't know whether anyone on the Trump campaign had colluded with Russia.
It's been a particularly bad stretch for Giuliani, who from the start has given disorienting media interviews that created negative headlines and provided ammunition to Trump's critics.
