Everyone in Washington is aghast that two party crashers elbowed their way this week into the White House state dinner.

Even more astonishing would be if someone isn’t canned — or perhaps prosecuted — over this monumental mess-up.

Tariq and Michaele Salahi weren’t invited to the state dinner, which President and Mrs. Obama hosted for the prime minister of India and his wife. But they got in. The word now is that a Secret Service employee let them enter without asking them for proper identification.

The Salahis apparently are reality-TV stars. So, perhaps this was a plot line that they would develop on their show — although I don’t know who’s watching it.

This is far worse than the Balloon Boy episode involving the parents who staged the fake drama a few weeks ago involving their son’s purported flight in a balloon over Colorado.

No, this one would could have turned out badly if the Salahis intended to do harm to someone — such as the president of the United States of America.

I don’t want to hear about the Secret Service employee being put on “administrative leave.” The Secret Service, the arm of the Treasury Department with duties that include protecting the Leader of the Free World, needs to get to the bottom of this matter in a New York minute and fire the individual who let the party crashers into a state dinner. And if there are grounds for a criminal prosecution, then pursue that option, too.

Get it done!
