Bad news doesn’t seem to come in trickles for Mayor Vince Gray’s administration, but in waves.

Today, the Post’s editorial board digs into yet another part of new Deputy Chief of Staff Andi Pringle’s past, finding that her work as a political consultant for a number of campaigns may not have been on the up-and-up:

[T]he firm she touts on her résumé, Pringle Communications Group Inc., is not in good standing with the D.C. government. Records from the city’s Department of Consumer and Regulatory Affairs show the firm’s articles of organization were revoked in November 2009 because it failed to file required reports. Yet even with its corporate status revoked, it apparently — according to information about recent clients on Ms. Pringle’s résumé — continued to operate. When we sought to ask why this might be, Ms. Pringle declined to speak with us.

If true, the news again calls into question how thorough the Gray administration’s new background checks are. Gray himself seems to be at least marginally concerned, telling WTOP’s Mark Segraves today that while he trusts Pringle’s answers on why she voted in D.C. while living in Maryland, he still needs to learn more about her lapsed business license.
