IOS – How to hide “Siri app suggestions” in iOS

Edit: As of iOS 10 you can remove the news widget.

It is not possible in iOS 9. See this question for more information about turning all/news suggestions off. Removing news headlines from Spotlight Search in iOS 9

Finally figured it out!!! That person a long time ago had invited me to a Facebook event that last many many days in a row. I never declined or ignored the event and I also had my iOS calendar set to show Facebook events. I declined and ignored the event in Facebook, he still appeared, but I didn't wait long (maybe that takes a while to refresh). I was impatient so I just turned off showing my Facebook events in the calendar app all together. He finally disappeared.
