WASHINGTON - The Latest on a House panel's expanding investigations of President Donald Trump (all times local):

2:35 p.m.

Three House committees are asking the White House and the State Department for any information on private conversations between President Donald Trump and Russian President Vladimir Putin, including an interview with an interpreter who sat in on their one-on-one meeting in Helsinki last summer.

The broad requests from the House intelligence, Foreign Affairs and Oversight and Reform committees ask for the substance of Trump and Putin's conversations in person and by phone and for information on whether those conversations had any impact on U.S. foreign policy. They are also asking whether Trump tried to conceal any conversations.

The committees ask for interviews with "linguists, translators or interpreters" who in any way listened to those conversations. Trump and Putin met privately in Helsinki in July for more than two hours with only interpreters present.

President Donald Trump says he'll co-operate with the House Judiciary Committee's sweeping investigation into his White House, campaign and businesses.

When a reporter asked him Monday if he was going to co-operate with the investigation led by Committee Chairman Jerrold Nadler, Trump replied: "I co-operate all the time with everybody. You know, the beautiful thing, no collusion. It's all a hoax."

The committee is sending requests to 81 people linked to the president and his associates.

Nadler said Monday the investigation will be focused on possible obstruction of justice, corruption and abuse of power.

Trump answered the question while he hosted the Division 1-winning North Dakota State University football team at the White House.

The House Judiciary Committee is launching a sweeping new probe of President Donald Trump, his White House, his campaign and his businesses. The panel is sending document requests to 81 people linked to the president and his associates.

House Judiciary Committee Chairman Jerrold Nadler says the investigation will be focused on obstruction of justice, corruption and abuses of power. The aggressive, broad investigation could set the stage for impeachment, although Democratic leaders have pledged to investigate all avenues and review special counsel Robert Mueller's report before taking drastic action.

Nadler said Monday's document requests are a way to "begin building the public record" and the committee has the responsibility to investigate.

The White House says it has received the House Judiciary Committee's letter requesting documents related to the Trump administration, family and business as part of an expanding Russia investigation.

White House press secretary Sarah Sanders said Monday that the White House counsel's office and relevant officials will review the letter and respond at the appropriate time.

The committee is requesting documents from more than 60 people.

House Judiciary Committee Chairman Rep. Jerrold Nadler, D-N.Y., who says he believes the president obstructed justice, says the panel wants to review documents from the Justice Department, the president's son Donald Trump Jr. and Trump Organization chief financial officer Allen Weisselberg. He says former White House chief of staff John Kelly and former White House counsel Don McGahn also are likely targets.
