A special assistant to the president — the president who recently lamented that an inability to pass gun control was one of the great failures of his administration — was arrested Friday after she allegedly fired a pistol at her boyfriend during a domestic dispute. Barvetta Singletary, 37, didn’t help advance her boss’ crusade against gun violence when she invited her boyfriend, a Capitol Hill police officer, over to her house for sex. Afterwards, she accused him of seeing another woman and demanded to see the texts on his cellphones. When he refused, Singletary reached into her boyfriend’s bag, according to the arresting documents, and pulled out the two cellphones and his service weapon, a .40-caliber Glock 23. She demanded he tell her the passwords to the phones. He refused. “Your phone is more important than me holding the gun on you,” she said, shooting the couch where he was sitting. Singletary was the Obama administration’s House legislative affairs liaison and was paid $125,000 a year. Let’s just say she wasn’t a low-level staffer. And her purposeful gun crime while working for this gun-hostile administration is more important than the time Dick Cheney accidentally shot a friend while hunting. But which one received more news coverage?
