Where are we with the Mueller investigation?

It's been nearly 20 months since Robert Mueller began his special counsel investigation of Russian interference in the 2016 United States presidential election. Over the weekend, a federal judge in Washington, D.C., agreed to extend the term of a grand jury hearing testimony in the investigation, just before its initial 18-month term expired.

Also this week, lawyers for former Trump campaign chairman Paul Manafort failed to properly redact a court filing, publicly revealing new details about evidence that Manafort shared campaign information with a Russian contact during the campaign.

And on Wednesday, there was confusion over how long Deputy Attorney General Rod Rosenstein, who appointed the special counsel, plans to stay at the Justice Department after a new attorney general is confirmed.

As America awaits Mueller's revelations, MPR News host Kerri Miller spoke with former Watergate prosecutor Nick Akerman, and Ciara Torres-Spelliscy, a Brennan Center fellow and law professor at Stetson University, about what we know so far and what we can expect from the investigation once it concludes.
