US President Donald Trump on Monday spoke about his administration's illegal immigration crackdown and anti-drug operations, and mentioned that nations unwilling to take back deported migrants eventually agreed after being warned of tariffs by Washington.

He also claimed a significant fall in fentanyl smuggling across US borders and lauded the American law enforcement for their service to the country. He made the remarks as he hosted his second 'Rose Garden Club' dinner in honour of Police Week at the White House.
