While the order immediately drew fire from LGBTQ+ advocates, Delaware Rep. Sarah McBride, the first openly transgender person elected as a state senator, dismantled its premise with sharp humor and undeniable science.

Trump announced his anti-trans order on his first day in office.

In light of President Donald Trump's executive action declaring that there are only two genders, Congress' first openly transgender Congresswoman Sarah McBride reacts.
