With Boston Globe columnist Kevin Cullen’s fate in the hands of outside investigators, I thought I would pull together what we know so far. I’ll begin with an internal memo that editor Brian McGrory sent to the staff late last week, a copy of which I obtained from several sources. We talked about the memo Friday on “Beat the Press” (above).

I hope you can understand our desire to seek facts before we address the assertions that have been publicly raised about the work of our colleague, Kevin Cullen. That said, I want to offer an update on the process. We’ve enlisted Kathleen Carroll and Tom Fiedler to oversee the review. Their involvement will help assure objectivity as well as speed. Kathleen is the former executive editor of the AP and someone universally respected across the industry. Tom is the dean of the BU College of Communication, the former executive editor of the Miami Herald, and someone whose calling card has always been his integrity. In addition, Daniel Okrent, the former public editor of the New York Times, has agreed to read their report and weigh in as necessary.

The review will consist of two-prongs. First, Kathleen and Tom will focus on marathon-related issues. Separately, we’re undertaking a broader review of Kevin’s work, initially in-house, but we’ll bring in outside help if needed. The first part I’m hoping will be completed within a couple of weeks.

You may see Kathleen and Tom around the newsroom. If they seek your help, please give it to them.

This work, unpleasant as it is, is important to our institutional credibility. I’ll be back to you again when I have more to report.

The investigation was prompted by Cullen’s April 14 column marking the fifth anniversary of the Boston Marathon bombings. The column has several problems. First, a reader would almost certainly think Cullen was claiming that he was at the finish line in 2013, even though he has said on other occasions that he was about a mile away. As I’ve said several times, the language strikes me as deliberately ambiguous, as though Cullen wanted to create that misimpression, even though he doesn’t come right out and say it. Second, there are apparent reporting errors as well, particularly regarding the actions and identities of the firefighters he mentions.

All of this has been fodder for two weeks on the “Kirk and Callahan” show on WEEI Radio (93.7 FM), which was the first to pick up on the discrepancies. The full details can be found in this blog post by Minihane, which combines fact, speculation (“It may be all true, though I seriously doubt it,” he wrote of a different Cullen column), and vitriol. But give Minihane his due. There are real problems with Cullen’s column, and we wouldn’t be here if not for WEEI. Cullen has been placed on paid leave pending the outcome of the investigation.

We talked about the Cullen situation on “Beat the Press” last Friday, April 20, and again on April 27 (clip above). Last week my colleague Emily Rooney added her own analysis, reporting that WEEI deceptively edited a Cullen interview that appeared in an HBO documentary. In the more recent clip, we all agreed that the Globe should be more transparent in letting the public know what’s going on beyond this editor’s note, which was published a week ago online and in print.

Also last week, Don Seiffert of the Boston Business Journal reported on the investigation and spoke with Marcus Breen of Boston College and me. Make of it what you will, but I was struck that Bill Richard, father of the late Martin Richard, whose family is mentioned in Cullen’s column, declined through a spokeswoman to comment.

And that, for the moment, is where things stand. As for myself, I’m a longtime admirer of Cullen’s work. Though I don’t know him personally, we’ve exchanged a few friendly greetings over the years. We should all be willing to wait and see if the investigation finds that the April 14 column represents a momentary lapse — or is an example of something more pervasive.
