Howard Kurtz has the latest on ABC News’s disputed report on Dennis Hastert:

Reporters for NBC, CBS, CNN, Fox News and other news organizations checked out ABC’s report but were waved off by law enforcement officials. “Within 15 minutes, we had three or four basic denials saying in effect this was a complete overreach, and we chose not to run it,” said John Reiss, executive producer of “NBC Nightly News.”

No other television news organization could find sources to confirm this story. The Department of Justice issued an extremely rare public denial — not once, but twice. And Hastert is threatening to sue.

ABC News is looking increasingly isolated on this.
