WASHINGTON — The Latest on the investigation into possible contacts between the Trump campaign and Russia in the 2016 election (all times local):

1:05 p.m.

Longtime Trump associate Roger Stone has concluded an interview with the House intelligence committee after more than three hours. Stone says he told lawmakers that he’s aware of “no evidence whatsoever” that there was coordination between the Trump campaign and Russia.

Stone told reporters Tuesday after the meeting that the majority of lawmakers’ questions focused on his communications with Guccifer 2.0, the unnamed hacker who has taken credit for breaking into Democratic National Committee email servers. He said questions also focused on communications he had through an intermediary with WikiLeaks founder Julian Assange.

Stone spoke to the panel as part of an investigation into Russian interference in the U.S. election. He said that he has had no contact with Special Counsel Robert Mueller, who is also conducting an investigation.

The House intelligence panel will interview two of President Donald Trump’s associates behind closed doors this week as congressional committees step up their investigations into Russian meddling in the 2016 election.

Longtime Trump associate Roger Stone and former staffer Boris Epshteyn will talk to the House panel. Stone confirmed his interview, which will be held Tuesday. Epshteyn also will speak to the committee this week, according to a source familiar with the interview. The person declined to be named because the panel’s meetings are private.

The interviews come as the House and Senate intelligence panels are looking into the meddling and scrutinizing the spread of false news stories and propaganda on social media. The Senate Intelligence committee will speak to officials from Twitter on Wednesday, also behind closed doors.
