So he did.  Utilizing a convenient excuse.

Holder cancels appearance in OKC amid angry protests

by Kelly Riddell

Attorney General Eric Holder canceled his appearance before the Oklahoma City Police Department’s graduating cadet class Thursday amid angry protests over his scheduled visit.

Mr. Holder was scheduled to deliver remarks at the graduation ceremony at 2:30 p.m. ET, according to his official itinerary sent out by the Justice Department Thursday morning.

Mr. Holder’s scheduled visit to Oklahoma City drew the criticism of several conservative lawmakers who planned the protest anticipating his arrival, including state Rep. Paul Wesselhoft, Republican, who has stated he believes that Mr. Holder should be impeached.

“Our protest has turned into a victory celebration because we frankly didn’t want him here — and we succeeded,” Mr. Wesselhoft said in an interview. “This man has used his position to advance his own political agenda and that’s not right. He swore to uphold the U.S. Constitution and defend it for all of us — not some of us.”

Carla Russell, one of the about 100 activists who came out for the rally, held a sign that read: “Holder is a Terrorist.”

So here comes the excuse:

But an early meeting at the Justice Department delayed Mr. Holder’s departure from Washington, causing him to miss the graduation ceremony, spokesman Brian Fallon said in an e-mail.

Bullshit alert.  It was pushback on a racist extremist, plain and simple.

Perhaps a few more facts are required, per the article:
