The Washington Post reported on Monday that Trump had divulged highly classified intelligence to the Russian officials during the meeting. Reports on Tuesday revealed that Israel was the source of that intelligence.

Putin's offer raises questions of whether the Kremlin actually has a transcript of the meeting and, if so, how it might have obtained it.

The House and Senate Intelligence committees are currently investigating Russian efforts to meddle in the 2016 presidential election, as well as the Trump campaign's alleged ties to Moscow.

Recently fired FBI Director James Comey revealed in March that his agency is conducting its own probe into the matter.
