There have been plenty of examples in the past 10 days.
The Obama administration's Justice Department issued a sweeping demand for two months of office, cellular and home telephone records from multiple Associated Press reporters and editors to investigate an alleged breach of national security.
The AP story in question, on a foiled terrorist plot, had been withheld for days at the request of the CIA. It finally went out on the wire on a Monday, after the AP was told that administration spokesmen would officially announce it the next day.
That tends to undercut Attorney General Eric Holder's claim that the story was based on one of "the top two or three most serious leaks that I have ever seen" and "put the American people at risk, and that is not hyperbole."
I don't think enough facts are known to conclude that Holder was wrong. But it does seem likely that the AP material was less damaging to national security than some stories The New York Times ran despite pleas from the George W. Bush administration.
Those were not followed by the kind of intrusive investigation launched in this case. You might not know it from reading much of the press, but Obama's administration has been much more aggressive in investigating leaks than Bush's ever was.
Another chill came from the targeting of conservative organizations by Obama's Internal Revenue Service. IRS agents were selectively refusing to give tax-exempt status to organizations with "tea party" and "patriot" in their names.
Anti-abortion groups were asked to pledge that they would never picket Planned Parenthood clinics. Organizers were asked numerous personal questions, including what they said in their prayers. If that's not chilling, I don't know what is.
The acting director of the IRS was told about this activity in May 2012, and the chief counsel and deputy secretary of the Treasury Department were informed in June 2012.
Did they pass the information along to Treasury Secretary Timothy Geithner? Did he tell the president? Did the president ever ask?
The excuse given in some quarters is that in some cases IRS agents acted on their own or contrary to instructions. That may be plausible.
As my Washington Examiner colleague Timothy Carney has pointed out, personnel at the IRS are heavily Democratic. That's probably true of most domestic government agencies.
