After touching down in the Iraqi capital on February 5, Pete Hoekstra noted that he had BlackBerry service. "Just landed in Baghdad," he tweeted. "I believe it may be the first time I've had bb service in Iraq."
The hapless congressman then detailed his itinerary across the country in real time, notifying his followers of the precise moment that he landed in the Green Zone as well as the timing of his return to America.
Before embarking on the trip, the House Intelligence Committee member was explicitly warned to keep his whereabouts a secret for security reasons.
Ignoring that advice, Congressman Hoekstra buoyantly announced: "Heading to Iraq and Afghanistan weds night. I'll update on twitter and web pg as links are available. I'll ne [sic] back in touch mid next week."
By far his biggest blunder was revealing the timing of his entry to the Green Zone - home to the heavily-fortified US embassy and scene of constant suicide bomb and mortar attacks against diplomatic convoys.
Hastily mounting his defence after CQ Politics broke news of the gaffe, the Republican hit back on decidedly party-political lines.
"President Obama, Speaker Pelosi, Secretary Clinton, and even Chairman Reyes are among the many Democrats who have announced their travel to Iraq or other sensitive destinations before arrival or while in country," he noted.
And true to form, the congressman publicised his defence by tweeting it to his pals: "Check my web site for response to twitterversy!" he beamed.
The lawmaker is not the first person to spur criticism for their obsessive use of Twitter. Mike Wilson hit the headlines last year after using it to announce that he had been in a plane crash, prior even to fleeing the wreckage.
The incident is also reminiscent of a blunder by moustachioed Fox News correspondent Geraldo Rivera, who was deported from Iraq after breaking an embargo on reporting troop movements during the 2003 invasion.
