Attorney General Eric Holder talks with Capt. Ron Johnson of the Missouri State Highway Patrol at Drake’s Place Restaurant in Florrissant, Missouri August 20, 2014. Holder visited Ferguson, Missouri, on Wednesday, hours after nearly 50 protesters were arrested in the 11th straight night of demonstrations over the August 9 fatal shooting of Michael Brown, an unarmed black teenager, by a white police officer. The St. Louis County prosecutor’s office will also begin presenting evidence on Wednesday to a regularly seated grand jury investigating the shooting death of Brown.

Here’s a look at tomorrow’s top talkers from Washington Post reporters and columnists who know the topics best.

FERGUSON LATEST: Gov. Jay Nixon announced the Missouri National Guard will begin withdrawing from Ferguson because conditions have improved. A Post video captures the hurt, anger and hope expressed by many of the African-American men in Ferguson.

MCDONNELL TRIAL DAY 19: Bob McDonnell said he had “no idea” that Jonnie Williams had taken his wife on a $20,000 designer shopping spree in New York in April 2011 even though he was in the city with them at that same time. McDonnell testified Thursday that he had only met the businessman three or four times before, though Maureen McDonnell, who arranged the get-together, had an interest in Williams and his nutritional supplement company, reports Matt Zapotosky. Petula Dvorak explores how women are still, by and large, the “trailing” spouse, the one who sacrifices to follow the other with the bigger and better job prospect.

POLITICS: Sen. Rand Paul spent two and a half days in Guatemala–-never before has a U.S. senator and potential future presidential candidate traveled so elaborately to a third world country as part of a medical mission, reports Ed O’Keefe. Philip Bump looks at three patterns that emerge when comparing the presidential vote over time to the Senate vote to see what it says about who will win the Senate in 2014.

JAMES FOLEY/RANSOMS: In practice, however, the United States and Britain appear to be inconsistent in their refusal to pay ransoms, and many other nations appear to find loopholes. So why pay ransoms at all? The horror of Foley’s death is why. Few politicians want to explain to a family that they could have saved a hostage but didn’t. The political fallout also could be huge, reports Adam Taylor.
