The last several years have brought a parade of dark revelations about the George W. Bush administration, from the manipulation of intelligence to torture to extrajudicial spying inside the United States. But there are growing indications that these known abuses of power may only be the tip of the iceberg. Now, in the twilight of the Bush presidency, a movement is stirring in Washington for a sweeping new inquiry into White House malfeasance that would be modeled after the famous Church Committee congressional investigation of the 1970s.

In a release Thursday, House Judiciary Committee Chairman John Conyers (D-MI) announced he will hold a hearing July 25 examining “the imperial presidency of George W. Bush and possible legal responses.”

The word “impeachment” was not mentioned in the announcement, but it appears the hearing is going to examine issues raised by Rep. Dennis Kucinich (D-OH) in his resolution to impeach Bush.

“Over the last seven plus years, there have been numerous credible allegations of serious misconduct by officials in the Bush Administration,” Conyers said in a news release.

The Army general who led the investigation into prisoner abuse at Iraq’s Abu Ghraib prison accused the Bush administration Wednesday of committing “war crimes” and called for those responsible to be held to account.

“After years of disclosures by government investigations, media accounts and reports from human rights organizations, there is no longer any doubt as to whether the current administration has committed war crimes,” Taguba wrote. “The only question that remains to be answered is whether those who ordered the use of torture will be held to account.”

If it wasn’t clear before it should be now: the Bush Administration can’t afford to attack Iran. With gas already at $4 a gallon and rising almost every day, Iran figuratively and literally has the United States over a barrel. As much as the Administration is tempted, it is not about to test Iran’s promise to “explode” the Middle East if it is attacked.

The Iranians haven’t been shy about making clear what’s at stake. If the U.S. or Israel so much as drops a bomb on one of its reactors or its military training camps, Iran will shut down Gulf oil exports by launching a barrage of Chinese Silkworm missiles on tankers in the Strait of Hormuz and Arab oil facilities. In the worst case scenario, seventeen million barrels of oil would come off world markets.

A New York Times article detailed the connection between numerous media military analysts and the Pentagon and defense industries, reporting that “the Bush administration has used its control over access and information in an effort to transform” media military analysts “into a kind of media Trojan horse – an instrument intended to shape terrorism coverage from inside the major TV and radio networks.”

A Media Matters review found that since January 1, 2002, the analysts named in the Times article – many identified as having ties to the defense industry – collectively appeared or were quoted as experts more than 4,500 times on ABC, ABC News Now, CBS, CBS Radio Network, NBC, CNN, CNN Headline News, Fox News, MSNBC, CNBC, and NPR.
