Clinton checks her phone at the opening of the Libyan Conference on March 29, 2011 in London, England. Hillary subtweets Jeb on worker comment

Subtweets: They’re for politicians, too.

Hillary Clinton’s campaign slammed Jeb Bush late Wednesday for remarking that Americans need to work longer hours during his meeting with The Union Leader in New Hampshire — though not by name. In a tweet, Clinton’s campaign shared a graph from the left-leaning Economic Policy Institute showing wages stagnating as productivity has risen over the last four decades.

“My aspiration for the country and I believe we can achieve it, is 4 percent growth as far as the eye can see. Which means we have to be a lot more productive, workforce participation has to rise from its all-time modern lows. It means that people need to work longer hours,” Bush said.

Bush later clarified that he meant that Americans working part-time should have more opportunities to work more hours. On Thursday morning, he implied that Clinton has not been listening to the concerns of Americans working part-time jobs.
