US President Donald Trump joked about his impeachment during a trip to Iowa, ABC News reported.

The president again accused Democrats of seeking to destroy Kavanaugh since the moment he was announced.

"Last week they were saying impeach, for what? For what?" Trump said.

"And besides I have to go first right?" half-joking at his own expense. "Even though we’ve done nothing wrong except create one of the greatest economies in the history of our country."
