President Donald Trump introduced a new Democratic villain to his fans after the House Judiciary Committee sent out document requests to dozens of his associates.

Trump complained Tuesday morning about the new lines of investigation into his family's business and his presidency, and he mentioned Rep. Jerry Nadler, the House Judiciary Committee chairman, for the first time ever on his Twitter account.

"Now that they realize the only Collusion with Russia was done by Crooked Hillary Clinton & the Democrats, Nadler, Schiff and the Dem heads of the Committees have gone stone cold CRAZY," Trump tweeted. "81 letter sent to innocent people to harass them. They won’t get ANYTHING done for our Country!"

Trump has long feuded with Nadler, whom he once derided as "Fat Jerry," since their days in New York City.

Nadler, then a state assemblyman, helped kill Trump's proposed Television City development in the 1980s on Manhattan's Upper West Side.
