Apparently President Koroma of Sierra Leone, who had a range of public events set for DC this week, will not be traveling to the US after hurting his ankle while playing squash. He will have ministers and other officials representing him at the events he was scheduled to participate in.
Amongst other events in DC, President Koroma was scheduled to give an address at SAIS and hold a town hall meeting in Silver Spring. Just a few days ago, I had commended Koroma for his large array of public events.
