The president, in a series of three tweets Monday, addressed Americans who are protesting his temporary ban on refugees from seven Muslim-majority nations:

"Only 109 people out of 325,000 were detained and held for questioning. Big problems at airports were caused by Delta computer outage, protesters and the tears of Senator Schumer. Secretary Kelly said that all is going well with very few problems. MAKE AMERICA SAFE AGAIN! There is nothing nice about searching for terrorists before they can enter our country.

Why it matters: Scientists around the world are skeptical about Russia's claims. There is no published scientific data to back up Putin's claims that Russia has a viable vaccine — or that it produces any sort of immunity without significant side effects.
