"I confirm that he has been notified about the offer. Mr. Assange is now considering it in consultation with his lawyers in the US," Carlos Poveda Moreno said.
Assange, whose website leaked evidence of Democratic bosses conspiring to sideline Bernie Sanders during 2016 primaries, bashed the Senate Intelligence Committee last October for not hearing him out.
This month the panel handed him an invitation to testify via US embassy in London. Assange has been living at Ecuador’s UK embassy for six years for fears of being extradited to the United States where he is wanted for exposing US war crimes in Iraq.
His lawyer said cooperation by Ecuadorian President Lenin Moreno would be needed if the activist decides to testify. Moreno said last month he disapproved of Assange's activities after cutting his Internet connection in spring.
