After sweeping Tuesday's primaries in Maryland, Delaware, Pennsylvania, Connecticut, and Rhode Island [1], Donald Trump shifted his attacks from his Republican opponents to Democratic front runner Hillary Clinton.

"Frankly, if Hillary Clinton were a man, I don't think she'd get five percent of the vote. The only thing she's got going is the women's card," said Trump in his victory speech from Trump Tower. "And the beautiful thing is, women don't like her."

Clinton responded to his words (he had made similar comments days earlier) while giving her own victory speech in Pennsylvania — she won the same states as Trump except for Rhode Island, which went to Bernie Sanders.

"If fighting for women's health care and paid family leave and equal pay is playing the woman card, then deal me in," she said to a cheering crowd.

Her campaign tweeted the exchange:

Caught your speech, @realDonaldTrump [2]. About that "woman's card"...https://t.co/kKaHWISchy [3]

Women on Twitter were also quick to react to Trump's comments:

My #womancard [5] always get's me things. Things like being ignored, less earnings... you know, things.

Ladies, the #womancard [16] gives you a 21% discount on your salary.

On Wednesday morning, Trump commented on Clinton's reaction. "I haven't quite recovered — it's early in the morning — from her shouting that message," he said in an interview with MSNBC [18]. It's not the first time Clinton has been criticized for shouting [19] or been "mansplained" to [20].
