WASHINGTON — The Latest on the investigations into Russian meddling in the 2016 election (all times local):

12:49 p.m.

The chairman of the Senate intelligence committee says the panel is continuing to investigate possible collusion between Russia and associates of the Trump campaign, but has not reached a conclusion yet.

Sen. Richard Burr, a North Carolina Republican, gave an update Wednesday on the committee’s investigation into Russian interference in the 2016 presidential election. He was joined by the committee’s top Democrat, Sen. Mark Warner of Virginia.

Burr says the committee has interviewed more than 100 witnesses as part of its investigation and that more work still needs to be done.

He says “the issue of collusion is still open.”

11:10 a.m.

Leaders of the Senate intelligence committee are set to release preliminary findings about Russian intervention in the 2016 election — and publicly warn states, voters and social media companies about how to prevent any future meddling.

Republican Sen. Richard Burr of North Carolina and Democratic Sen. Mark Warner of Virginia will speak to reporters in the Capitol Wednesday. The idea is to lay out what some of what the committee has found as the 2018 midterm elections approach.

Since Burr and Warner began the investigation in January, the panel has interviewed dozens of intelligence and political officials to assess the extent of Russian interference in last year’s election. The committee, along with several others in Congress, is also investigating any connections between the Russian meddling and President Donald Trump’s campaign.
