(CNN) The White House said on Wednesday it is entertaining a proposal raised by Russian President Vladimir Putin to interrogate Americans in exchange for assistance in the ongoing US investigation into election interference, putting the White House at odds with the State Department.

Putin raised the idea in his summit talks with President Donald Trump on Monday, according to White House press secretary Sarah Sanders. The Americans wanted for questioning by Moscow include Michael McFaul, the former US ambassador to Russia, and American-born financier Bill Browder, who successfully lobbied the US government to impose new sanctions on Moscow.

Sanders indicated on Wednesday no final decision had been made but that the proposal was under consideration.

"The President's going to meet with his team and we'll let you know when we have an announcement on that," she said.
