WASHINGTON (AP) — The Senate intelligence committee has postponed an open hearing with President Donald Trump's personal lawyer.

Michael Cohen was scheduled to testify next week as part of the panel's investigation into Russian meddling in the 2016 election and whether Trump's campaign was involved.

The committee wouldn't say why Wednesday's meeting was delayed. Committee Chairman Richard Burr of North Carolina and Virginia Sen. Mark Warner, the top Democrat, said the panel "appreciates Mr. Cohen's cooperation."

Burr and Warner called off a closed-door interview with Cohen last month after he sent a statement to the media, saying they'd asked him not to comment. They then scheduled the public hearing.

His testimony was expected to focus in part on his involvement in a discussion during the campaign to develop a Trump Tower in Moscow.
