Washington is a well-oiled machine. A town that follows a pattern and runs like clockwork. The president is elected every four years in November. Congress begins a new session in January. The White House Correspondents’ dinner is held every spring.

And just as everyone in D.C. knows when to expect those events, everyone knows that as of Thursday, Aug. 1, we enter the dog days of summer — as if with the turning of a calendar page, news suddenly slows.

But does it really? It is true that Congress is out. There are no hearings. And even the president can be expected to leave town for a while. But just because there isn’t much news, doesn’t mean there is no news.

According to longtime CBS White House correspondent Mark Knoller, who keeps extensive notes on presidential happenings, many newsworthy events have popped up in August, including several important events in every presidency.

And even though the news media have dutifully covered these events, they are also the ones maintaining the dog days myth.

When August news does happen, it is often handled differently, Knoller observed. With fewer events to cover, what does take place during the dog days is magnified. And the way the president handles his duties while on vacation becomes of increasing interest to the press.

“As soon as something happens it is, ‘Was the president told about this? What time was he awakened?’ ” Knoller said.

World history never stands still, of course. On Aug. 14, 1945, President Harry Truman announced victory over Japan in World War II, so we get V-J day as a mid-August marker. And this year marks the 50th anniversary of the March on Washington, proof that hundreds of thousands of people made news and witnessed civil rights history during these dog days.

In recent years, the slow weeks of late summer have featured plenty of political news, Washington-related pop culture and even a few events that demand a presidential response. A look at Augusts past proves that while everyone might try to head to the beach, news can often interrupt.
