“I think it could very well have been Russia, but I think it could well have been other countries,” Trump said at a joint news conference in Warsaw with Polish President Andrzej Duda. “Nobody really knows. Nobody really knows for sure.”Trump has also accused his predecessor, Barack Obama, of not doing enough to respond to the allegations of Russian hacking.

Later Friday, Rep. Adam Schiff (D-Calif.), the top Democrat on the House Intelligence Committee, which is investigating Russia meddling, also weighed in.

“Yes, I’m sure that’s the big talk at G20,” Schiff wrote on Twitter. “Not climate change or trade, but why didn’t John Podesta give a server that wasn’t his to the CIA.”
