Fillon pledges to maintain state of emergency

I think there may be some confusion here. François Fillon is a French politician who was a candidate in the 2017 French presidential election, but he did not pledge to maintain a state of emergency.

In fact, the state of emergency in France was declared in November 2015 in response to a series of terrorist attacks, and it was lifted in November 2017, shortly after the presidential election.

It's possible that you may be thinking of another politician or event. If you could provide more context or clarify what you are referring to, I'd be happy to try and help you further.
