That’s not the way the U.S. attorney sees it, though. Greg Fouratt sent a letter to defense attorneys, the AP reports, in which he said the fact that no charges were filed “is not to be interpreted as an exoneration of any party’s conduct.” He also said the investigation “revealed that pressure from the governor’s office resulted in the corruption of the procurement process.”

It’s not great form for a prosecutor to be talking guilt out of court when there weren’t even any indictments, but that’s not likely to matter politically. Rather than being able to go on from here free and clear, Richardson will have to deal with that letter hanging around his neck for some time.

In another statement, this one released Friday, Gallegos said Fouratt’s letter “is wrong on the facts and appears to be nothing more than sour grapes.”

ABC News is now reporting that Clinton also met with the jailed reporters, Laura Ling and Euna Lee. A government source described the meeting as highly emotional but told ABC that those on Clinton’s team in North Korea are hopeful the journalists could be released as early as tomorrow.

Clinton has a loose connection to the jailed reporters. Both work for Current TV, a news and media venture headed by Clinton’s former vice-president, Al Gore. Ling and Lee were arrested on the border between North Korea and China in March. In June, they were sentenced to 12 years of hard labor for what North Korea said was their illegal entry into the country, as well as engaging in undefined actions deemed hostile to the communist country.

The White House has thus far remained reserved when discussing Clinton’s trip. North Korean media said Clinton shared a message from President Obama, but White House Press Secretary Robert Gibbs released a statement in which he said, “While this solely private mission to secure the release of the two Americans is on the ground, we will have no comment … We do not want to jeopardize the success of former President Clinton’s mission.”

However, Sen. Lindsey Graham, R-S.C., seemed somewhat confused by the decision to send Clinton. On the “Today” show this morning, he said of Clinton’s visit that “I don’t know what this is,” though he expressed hope that the visit could lead to progress on limiting North Korea’s nuclear arsenal.

There is a long history in the U.S. of notable political emissaries traveling across the globe to try to free hostages.

Perhaps the most memorable diplomatic mission was the Rev. Jesse Jackson’s 1999 trip to Belgrade to ask for the release of three U.S. soldiers held as prisoners of war by then Yugoslav president (and war criminal) Slobodan Milosevic. The trip was controversial because Jackson made the journey without the blessing of the Clinton White House. That he actually convinced Milosevic to release the soldiers after the Clinton administration had been unable to do so made Jackson’s fame as a hostage-release negotiator grow. The civil rights leader has worked as a diplomat in similar circumstances numerous times over his career: He was able to get hostages released from Syria in 1984, from Cuba in 1987 and from Kuwait and Iraq in 1990 — all without official presidential or congressional approval.

New Mexico Gov. Bill Richardson, who had been discussed as a possible liaison to negotiate the return of Lee and Ling, brokered the release of U.S. hostages from North Korea in the 1990s. Richardson has also helped secure the release of hostages from Iraq, Cuba and Sudan and most recently met with Venezuelan President Hugo Chavez to seek his support in getting a Colombian Marxist guerrilla group to release three U.S. contractors they’ve detained since 2003. Colombian commandos eventually freed the hostages, along with Ingrid Betancourt, in June 2008.

And in one of the most embarrassing hostage situations the U.S. ever faced, President Jimmy Carter proved unable to negotiate with Iran for the release of 52 Americans held after the overthrow of the shah during the Iranian revolution. A daring military operation to free the hostages also failed. Iran eventually released the hostages once President Ronald Reagan took office. Later in his presidency, Reagan suffered a major political scandal when it was revealed that his administration had sold arms to Iran in an attempt to gain the release of seven American hostages being held in Lebanon by Iranian terrorists.

Still, Richardson made clear that he doesn’t believe this is the end of his political career. Referencing a statement from Barack Obama in which the president-elect said he “look[s] forward to his future service to our country and in my administration,” Richardson said, “I still believe I have a future in public service.”

There was one odd note Monday afternoon. When one reporter asked Richardson — who’d previously said he would not take any questions related to the CDR investigation — whether he had a lawyer, the governor responded, brusquely, “I am not getting into any more questions,” and the press conference was over.
