(CNN) On most weekdays at the White House, reporters gather midday for the daily press briefing, a question-and-answer session that's gained new attention as President Donald Trump's administration gets underway.

In the James S. Brady Press Briefing Room — named for the Ronald Reagan aide who was shot during an assassination attempt in 1981 — reporters take their seats around 1 p.m. ET, which is usually around when the briefing begins. Seats are allocated by the White House Correspondents Association, but any credentialed member of the media can attend. In the first weeks of the Trump administration, the daily briefing has been standing-room only with reporters who don't have assigned seats.

The Press Secretary typically strides out a few minutes after the briefing's schedule start time. He begins by running through the President's schedule. Then the questions begin.

Trump's spokesman Sean Spicer, however, has called on a variety of outlets first, including the New York Post, One America News Network, and ABC News.
