Another clash between protesters and police lit up Ferguson, Mo., on Wednesday night, with police shooting tear gas into crowds and briefly arresting two journalists.

Reporters Ryan J. Reilly of The Huffington Post and Wesley Lowery of The Washington Post were briefly arrested while covering the protests after police entered a McDonald's where the two were working. Reilly tweeted his arrest as several reports emerged that police on the scene were telling TV crews to leave.


President Obama was briefed on the situation by Attorney General Eric Holder and senior adviser Valerie Jarrett, White House spokesman Eric Schultz said.

A police spokesman told The New York Times that Molotov cocktails were thrown, according to police on the scene, and that at least 10 people had been arrested.

"Oh, God," Ferguson Police Chief Thomas Jackson said when told of the reporters' arrests by the Los Angeles Times. "I told them to release them," Jackson said of the two reporters. His department was in command.

Many questioned where Missouri Gov. Jay Nixon (D) was amid the protests.

Several hours later, he tweeted that he was "canceling all appearances" at the Missouri State Fair to visit the area Thursday.
