This evening, explosive new details are emerging in the Fast and Furious scandal that led to the contempt vote yesterday against Attorney General Eric Holder.

The Daily Caller reports tonight:

House oversight committee chairman Rep. Darrell Issa and Iowa Republican Sen.  Chuck Grassley are asking the Department of Justice’s internal investigator to hold accountable anyone who retaliated against or threatened to retaliate against Operation Fast and Furious whistleblowers.


The two lead Fast and Furious investigators also released new, never-before-public documents that show officials in ATF’s Washington headquarters were trying to cover up Fast and Furious two weeks before Grassley  ever even asked about it.

Grassley didn’t confront the Justice Department or ATF with those questions until Jan. 27, 2011, but ATF headquarters had prepped internal talking points as early as Jan. 12, 2011.

In that Jan. 12, 2011, memo, ATF officials laid out expected questions about gunwalking in Fast and Furious and Border Patrol agent Brian Terry’s murder with Fast and Furious weapons – and canned answers ATF officials were supposed to  give to press or anyone else asking about it.

Twitter has exploded this evening as news of this development and secret Dept. of Justice wiretaps came to light on Friday.

Progressives on Twitter are also increasing their desperate attempts tonight to shift blame away from Holder and President Obama and onto former President George W. Bush or the National Rifle Association.

The bait and switch blame operation is now being spearheaded by U.S. Rep. Elijah Cummings, Issa’s Democratic counterpart of the House Oversight Committee.

Of course lost in all of the blame-shifting by the Left is concern about the deaths of Border Agent Brian Terry and Immigration and Customs Enforcement agents Jaime Zapata and Victor Avila and scores of Mexican civilians.
