Anyway, he has also fired the man investigating his connections to Russia, and after his staff have said it is nothing to do with this investigation, he has said it is. And there is the issue of him allegedly asking Comey to drop the investigation, and then, after people said he did not give classified information to Russia, he admitted to doing so.
The thing is that he was elected despite his links to Russia, not just the things that he has said in the past about Russian links, but also his call to Russia to hack the emails of Clinton before the election (calling for a foreign power to take part in espionage to influence an election). That may be dismissed as a joke, as can the allegations that he paid prostitutes to urinate on a bed that Obama has slept in when he had been in Russia.
So, does it really matter to the people of America if he has links to Russia?
Of course it matters to the Baltic nations, and us in the UK, but does it really matter to America to work more closely with Putin?
