A Times news article reports that Douglas Schoen in 2011 registered as a lobbyist for a Ukrainian steelmaker. Mr. Schoen "had been on a $40,000-per-month retainer as an adviser to Mr. Pinchuk since 2000," the Times says.
Now they tell us! In 2012 the Times published an article by Mr. Schoen that identified him as "a political strategist and Fox News contributor. He is the co-author with Scott Rasmussen of Mad as Hell: How the Tea Party System is Fundamentally Remaking Our Two Party System." That was the same identification the Times had on another article by Mr. Schoen that the paper published in 2011.
Mr. Schoen doesn't turn up in the Senate lobbying disclosure database, or at least he didn't when I searched. He does turn up in the Department of Justice's Foreign Agent Registration Act database.
The Times news article doesn't mention Mr. Schoen's opinion-writing for the Times, either.
Perhaps the little biographies at the end of Times opinion articles would be more useful to readers if they were more complete.
