On Monday, during Biden’s speech on economic issues, Allen sent at least six emails to her list, each with up to three tweets, chiefly observations from reporters about the remarks, one official told Yahoo News.

Including messages about breaking news stories, White House officials say, her daily total runs easily into the hundreds of emails, and many more when the president’s schedule includes a high-profile speech or a press conference.

While White House communications staff track her alerts closely, other officials have been known to route her messages into email folders and check them just a couple of times a day, one Obama aide said.

When Obama faces the media, it’s not uncommon for Allen to send out 10-12 emails, each rounding up five to six tweets just about the president’s opening statement. She will follow up with messages including notable tweets about each question asked and each response.
