(CNN) The anonymous whistleblower who filed a complaint with the intelligence community inspector general, which includes allegations about President Donald Trump's conduct, has tentatively agreed to meet with congressional lawmakers, according to correspondence obtained by CNN.

The meeting could take place on the condition that acting Director of National Intelligence Joseph Maguire approves appropriate security clearances for the individual's legal counsel so that they can accompany their client, the correspondence showed. Rep. Chris Stewart, a member of the House Intelligence Committee, said on Twitter late Wednesday night that the complaint had been declassified but the document was not immediately available publicly.

House Intelligence Committee Chairman Rep. Adam Schiff wrote a letter to Maguire making the request Wednesday after the whistleblower's lawyers agreed to meet with lawmakers if that condition is met and requested assistance in expediting approval from the acting DNI.

CNN reported Tuesday that the whistleblower's legal counsel "wrote to the Acting Director of National Intelligence to request specific guidance as to the appropriate security practices to permit a meeting, if needed, with the Members of the Intelligence Oversight Committees."

"This is a reasonable request that the Committee strongly supports and expects your office to fulfill immediately," Schiff wrote.
