DC residents are used to derision from chillier quarters of the country over their city’s occasional paralysis in the face of winter weather. After a few inches of snow and some early morning sleet in the first half of the week resulted in a wave of Washington-area shutdowns, the city’s most famous Midwestern transplant couldn’t resist a dig or two at his new hometown’s expense.
"My children's school was canceled today, because of what? Some ice," President Obama told a group of business leaders visiting the White House Wednesday.
"As my children pointed out, in Chicago school is never canceled," he said, adding that his daughter Sasha observed that schoolchildren there would even have recess outdoors.
The president joked that he would have to instill some “flinty Chicago toughness” into his neighbors. "When it comes to the weather, folks in Washington don't seem to be able to handle things.”
That lesson may have to wait for the next winter storm: after a late-day wave of precipitation, DC's forecast for tomorrow is sunny, with highs in the upper 30s.
