The Washington Post notes that, “Lawmakers say administration’s lack of candor on surveillance weakens oversight.”

Gee, you think?

Lawmakers tasked with overseeing national security policy say a pattern of misleading testimony by senior Obama administration officials has weakened Congress’s ability to rein in government surveillance.

Members of Congress say officials have either denied the existence of a broad program that collects data on millions of Americans or, more commonly, made statements that left some lawmakers with the impression that the government was conducting only narrow, targeted surveillance operations.

The most recent example came on March 12, when James R. Clapper, director of national intelligence, told the Senate Intelligence Committee that the government was not collecting information about millions of Americans. He later acknowledged that the statement was “erroneous” and apologized, citing a misunderstanding.

“Misunderstanding,” my ass.

Clapper was given a day’s notice that the question was going to be asked, and he was given an opportunity to further clarify immediately after the fact.

He simply lied, because he knew that he could.
