Just a few weeks after the Brussels terrorist attacks that killed 32 people and injured more than 300 others, London became the first major Western capital to elect a Muslim mayor.

Sadiq Khan was born in London shortly after his parents emigrated to the United Kingdom from Pakistan.

In May's mayoral election, Khan won a landslide victory after a contentious campaign. His Conservative opponent was widely criticized for attempting to link Khan to Islamic extremism because of his faith and past work as a human rights lawyer.

Last Friday, on his first foreign trip as mayor, Khan made Chicago his first stop and spoke with Chicago Tonight during an appearance at the tech hub 1871.
