Is the "Gunwalker" case as big as Watergate?: No one died in Watergate, "blatant lying" by the Justice Department?

Fox News has this:

The idea behind Fast and Furious, hatched in the ATF's Phoenix office, was to let so-called straw buyers purchase guns in the United States so they could be traced to big-time gunrunners in Mexico. But documents and testimony now show that U.S. officials lost track of thousands of guns, some of which later were found at the scenes of violent crimes, including the murder of a U.S. border agent.
On Friday, National Rifle Association President Wayne LaPierre accused Holder of stonewalling Congress.
"This is the biggest cover-up since Watergate, and it's time to ask the Watergate question. Who authorized Fast and Furious, and how high up does it go?" LaPierre asked during a speech to the Conservative Political Action Conference in Orlando.
According to a source close to the investigation, despite numerous subpoenas and demands for potentially thousands of pages of records, the Justice Department has turned over just 12 documents. Unless the House Oversight Committee can cut lose more incriminating documents from the Justice Department or additional whistleblowers come forward, the investigation could stall, said a person familiar with the situation.
So far, the scandal has produced headlines but only one resignation, that of the U.S. attorney in Arizona.
The paper trail however has revealed blatant lying by the Justice Department, which originally told Sen. Charles Grassley the ATF did not "walk" guns. That position conflicts with agent testimony and pages of internal emails.
A document obtained Friday by Foxnews shows the following agencies all had some hand in Operation Fast and Furious: ATF, IRS, DEA, ICE, the U.S. Marshall's Service, Phoenix police and the U.S. Department of Agriculture.
The operation allowed members of the Sinaloa Cartel to buy in excess of 1,900 weapons for more than $1.25 million dollars over a one-year period beginning October 2009, according to a briefing paper dated last January. . . .
An ATF whistleblower agent told Fox News the agency made "absolutely no attempt to follow the weapons." . . .
