Donald Trump is being urged by senior US politicians not to meet Vladimir Putin alone.
The US President is due to meet the Russian President in Helsinki, Finland, on Monday night (NZ time) for a one-on-one session.
Newshub Europe Correspondent Lloyd Burr told The AM Show there were some senior democrats who have written to Mr Trump advising him not to do it.
"Vladimir Putin is a trained KGB spy, a trained agent... who knows what he can get out of Donald Trump. He can use it against him and against the US.
"Donald Trump thinks he can handle it, and it is going to be fascinating to see what comes out of it."
Eight Democratic senators, including Minority Leader Chuck Schumer, wrote to the US President pleading with him not to try and 'wing it alone' and have other American officials there with him.
"Mr Putin is a trained KGB intelligence veteran who will come to this meeting well-prepared," the letter reads, according to Newsweek.
"As the Kremlin said last week, a one-on-one meeting with you 'absolutely suits' him. There must be other Americans in the room.
"Vladimir Putin wants to see the West divided and weakened... You must not play into his aims."
The letter also referenced the alleged Russian interference in the 2016 US Presidential election and that Mr Trump should press Mr Putin on what really happened.
The meeting is part of Mr Trump's brief European tour that took in the UK and a meeting with NATO.
Before he left, the US President said the meeting with Mr Putin would be "the easiest of them all".
