American, as well as the Intelligence Services of our allies, routinely surveil known Russian spies and operatives. They also do this against any hostile government’s agents. The British GCHQ was picking up ongoing discussions between Putin’s Bitch’s people and the Russian FSB starting in 2015. Meaning that collusion between the Russians and the Trump Campaign had been ongoing for nearly a year before the FBI finally got a clue. This is proof positive that criminal collusion was going on – and evidence that Trump committed treason.
What was in those conversations has not been made public, and is still classified.
It is well past time to impeach, convict, and hang this POS for his Treason.
