US President Donald Trump's wife Melania faced rare boos Tuesday when she gave a speech on the dangers of drug addiction in the east coast city of Baltimore. Not appearing to have been fazed by the booing, Trump began her remarks by thanking the students and other attendees for getting involved to fight the opioid crisis.
The goal is to help educate students, teachers and parents about opioid use and misuse. "I encourage you to use the resources available in your community so that nothing can stand in your way".
Her husband, President Donald Trump, has had a hard relationship with Baltimore.
It was in July the president tweeted his criticism of the city, calling it a place where 'no human being would want to live'.
He was met with protests in September, including by a giant inflatable rat, when he went to Baltimore to meet with House Republicans.
The First Lady was attending the B'MORE Youth Summit for Opioid Awareness, hosted by the U.S. Drug Enforcement Administration's 360 Campaign and the Mark Wahlberg Youth Foundation.
