Attorney General William Barr is scheduled to testify before the House Judiciary Committee after the Justice Department took the unusual step of intervening in Roger Stone's sentencing recommendation.

President Trump hailed Barr on Wednesday for making the recommendation.

Rudy Giuliani, President Trump's personal attorney, says the president should not back away from investigating Joe Biden even after Trump's expected acquittal Wednesday by the U.S. Senate.

"Absolutely, 100%," Giuliani told NPR's Steve Inskeep in an interview Tuesday. "I would have no problem with him doing it. In fact, I'd have a problem with him not doing it. I think he would be saying that Joe Biden can get away with selling out the United States, making us a fool in the Ukraine."

As jurors in President Trump's impeachment trial, senators have remained silent as House impeachment managers and Trump's defense team make their cases. But now they have their opening.

The trial adjourned on Monday, giving senators their chance to take the floor. That window was still open on Tuesday; senators had up to 10 minutes each to speak.

Senate Majority Leader Mitch McConnell, R-Ky., spoke first on Tuesday, dismissing the two articles of impeachment against Trump as "constitutionally incoherent."

In Iowa, voters expect candidates to come to them. Homes, churches and schools serve as intimate venues for presidential hopefuls to meet and greet with folks who could have an impact on the momentum of their campaigns.

"We expect to shake their hands, we expect to look them in the eye, we expect to be able to ask them the questions we care about," says Rachel Paine Caufield, a political science professor at Drake University in Des Moines.

House impeachment managers released their formal response to the summons sent by the Senate last week, a procedural part of the impeachment process ahead of the trial that begins on Tuesday.

"President Trump's conduct is the Framers' worst nightmare," they said in the brief released Saturday.
