Bernard Kerik, a close ally of former President Donald Trump and a key figure in the effort to overturn the 2020 election, has given thousands of documents to special counsel Jack Smith, his lawyer said Monday.

Kerik, a former New York police commissioner, worked closely with attorney Rudy Giuliani to investigate unfounded claims of voter fraud after Trump lost the election to President Joe Biden . Smiths team had subpoenaed Kerik for documents collected during the attempt to overturn the 2020 results, but the former commissioner had resisted those demands until the Trump campaign had reviewed the material for any privileged information.

I have shared all of these documents, approximately 600 MB, mostly PDFs, with the Special Counsel and look forward to sitting down with them in about 2 weeks to discuss, Keriks lawyer, Tim Parlatore, told CNN and NBC News in a statement .
