A spokesman for President Donald Trump's personal attorney acknowledged late Thursday that the lawyer, Marc Kasowitz, had sent “inappropriate” emails the previous evening to someone who had urged him to resign.

According to ProPublica, which published the emails on Thursday, Kasowitz sent profanity-laden messages to a retired public relations professional who said it was “in the long-term interest” of Kasowitz and his firm to step down from the president's legal team. Kasowitz replied to the man, whose name ProPublica did not publish, “You are fucking with me now” and “Let's see who you are […] Watch your back, bitch.”

Kasowitz also demanded the man call him and provided his cellphone number, then called the man a “piece of shit” twice.
