Clinton highlighted the latest merchandise being offered by her nonprofit Onward Together — a cap sporting the phrase “But Her Emails” — in an Instagram post and tweet on Friday.They’re described as “black unstructured dad hats” that are union-made in America.The most important element is the phrase, which is frequently used to slam back at the cascade of Trump’s continually emerging eye-popping behavior while president. Yet he acted positively outraged while campaigning against Clinton at her history of sending emails on a private service while she was secretary of state in the Obama administration. He still has his fans chanting “Lock her up!” because of the emails. She was cleared of wrongdoing after extensive investigations.Clinton wrote on Instagram that the new hats were being offered “just in time for Galentine’s Day, and the news that Trump was flushing documents down White House toilets.” (Galentine’s Day is a made-up holiday popularized in NBC’s “Parks and Recreation.”)Sen. Ted Cruz (R-Texas) tried to humiliate Clinton over the hats, responding in a tweet: “This is just sad.” But Twitter critics weren’t having it.
