Sen. John McCain: Putin the 'most important threat, more so than ISIS'

During a visit to Canberra, Senator McCain said Mr. Putin was the "premier and most important threat, more so than ISIS".

Admitting that Mr. Trump's administration had become enmeshed in scandal and the president's antics had unsettled his countrymen as well as friends like Australia, Senator McCain said the United States of America needed its allies more than ever.

Moreover, McCain added that he is concerned about reports that Trump's son-in-law Jared Kushner called for a secret communication channel with Russian Federation even before Trump took office.

He cited an attempt to influence the French election and said Russian Federation had "dismembered Ukraine, a sovereign nation" as reasons for viewing Putin as the greatest threat.

The differences between McCain, who heads the powerful Senate Armed Services Committee and is a former presidential candidate, and Donald Trump are longstanding and significant.

"I think ISIS can do awful things", he said.

"I have seen no evidence they succeeded but they tried and they are still trying".

McCain said he wants the Senate to pass stronger sanctions against Russian Federation.

"My friends, I know many Australians have questions about President Trump".

Mr McCain said Mr Trump accepted the advice of his team "most of the time". "We really are, and for me to tell you that we aren't, politically, is not fair", he said. "We haven't responded at all", he said. Hollywood satire becomes obsolete when you have this man.

Trump's relationship with Australia came under fire during the first days of his presidency in January, when reports of an uncomfortable phone call between Trump and Australian Prime Minister Malcolm Turnbull made waves.

"America is our Congress, which now has within it as many internationalists, both Republicans, and Democrats, as any Congress in which I have served".

The senator from Arizona urged allies to remember that the United States and its government was greater than a president, suggesting that patience and trust in its system would pay off.

Russian political scientist Boris Mezhuyev told Sputnik Radio however that despite all his flamboyance, McCain has essentially become the symbol of a serious crisis within the US Republican party.
