President Trump will have his first face-to-face meeting with Russian President Vladimir Putin during the G20 summit in Hamburg, Germany, later this week.

The high-stakes meeting comes amid several probes into alleged collusion between the Trump campaign and Russia during the presidential election.

On "Fox & Friends" this morning, David Bossie, who served as Trump's deputy campaign manager, said there is no evidence that any collusion took place, and the whole Russia story is being used by the Democrats for political purposes.

"That is the dangerous game that the Democrats are playing," Bossie said. "The Democrats continuously make this, I believe, into a dangerous situation."

He pointed out that Democrats and the media are already speculating on what Trump can and can't say during his meeting with Putin, which he argued could prevent the leaders from having an open and productive dialogue.

"I think this really is a game-changer over the last six months of what they've done to our relationship," Bossie said. "And it's dangerous and it's irresponsible by the Democrats."

"I find it quite frankly offensive that the Democrats, for political reasons, have made our relationship with Russia much more difficult to manage for President Trump."
