Michael Cohen paid $50,000 in “election-related” expenses to an unknown company for “tech services” during the 2016 presidential election, court documents said.

The payment by President Trump’s ex-personal lawyer was “related to work Cohen had solicited from a technology company during and in connection with the campaign,” according to legal documents released Tuesday.

It was not clear on Wednesday what the “tech services” were related to.

Cohen’s lawyer, Lanny Davis, could not immediately be reached for comment.

Special Counsel Robert Mueller is investigating whether the Trump campaign colluded with Russia on the hacking of the DNC and Clinton ally John Podesta.

The payment was first reported by CNBC.

Cohen pleaded guilty on Tuesday to paying hush money to two women on behalf of Trump.
