“At the end of the day, the president’s not going to be impeached over either of those two offenses” — Darrell E. Issa, Chairman of House Oversight and Government Reform Committee (Rod Lamkey Jr./The Washington Times)
The Obama administration sought to intimidate witnesses into not testifying to Congress on Tuesday about whether ATF knowingly allowed weapons, including assault rifles, to be “walked” into Mexico, the chairman of a House committee investigating the program said in an interview Monday.
House Oversight and Government Reform Committee Chairman Darrell E. Issa, California Republican, said at least two scheduled witnesses expected to be asked about a controversial weapons investigation known as “Fast and Furious”received warning letters from the Bureau of Alcohol, Tobacco, Firearms and Explosives to limit their testimony.
Mr. Issa’s committee is set to hear testimony from six current or former ATF employees, including agents and attaches assigned to the bureau’s offices in Mexico, about the operation — in which, federal agents say, they were told to stand down and watch as guns flowed from U.S. dealers in Arizona to violent criminals and drug cartels in Mexico.

Mr. Issa also said he is certain the Fast and Furious operation was known by most top officials at the Justice Department and that Attorney General Eric H. Holder Jr. either knew and misled Congress, or was so out of the loop that he’s guilty of mismanagement.
“How is it that the No. 2, 3, 4 at Justice all knew about this program, but the No. 1 didn’t?,” Mr. Issa said. “Is it because he said ‘don’t tell me’? Is it because they knew what they were doing is wrong, and they were protecting their boss? Or is it that Eric Holder is just so disconnected … ?
“Whichever it is — he knew and he’s lied to Congress, or he didn’t know, and he’s so detached that he wasn’t doing his job — that really probably is for the administration to make a decision on, sooner not later,” Mr. Issa said.
