Earlier in the day, Trump said that it was a "very scary time for young men in America" because women could accuse them of sexual assault or rape.

Violent sexual crimes are among the most under-reported crimes, in large part because victims tend to be shamed or disbelieved.

In between his various attacks on Dr. Ford, Trump has called her account "very credible" and said that she was a "very fine woman."

Trump has been accused of sexual assault or harassment by at least 19 different women. He has admitted to "grabbing women by the pussy" because he knew his fame and influence would let him get away with it.

Why does this matter?

• There is no political prize so important that it is worth scaring sexual assault victims from coming forward.

• Even by Trump's standards of lashing out at women who upset him, this is pretty awful. 

• The most charitable interpretation of Trump calling Ford both "very credible" and viciously attacking her as a liar is that he is mentally unstable.
