On today’s episode:

• Matt Apuzzo, a New York Times reporter who has been covering the Russia investigation, discusses the case against George Papadopoulos, a foreign policy adviser to the Trump campaign.

Background reading:

• Mr. Papadopoulos’s plea represents the most explicit evidence that the Trump campaign was aware that the Russian government was trying to help Donald J. Trump and that the campaign was eager to accept that help.

• Court documents released on Monday show how Mr. Papadopoulos repeatedly sought to set up a meeting between the Russian government and Mr. Trump and his campaign officials.

• The White House said that none of the charges proved that the president had colluded with Russia.

• If you missed the flurry of developments on Monday, here’s a wrap-up.
