In his first volley of tweets for the week, President Trump blamed protesters, Charles Schumer's "tears" and Delta's computer glitch for chaos at airports across the country in the aftermath of his executive order on immigration.He added that according to Secretary Kelly "all is going well with very few problems" and all-capped "MAKE AMERICA SAFE AGAIN""

"Only 109 people out of 325,000 were detained and held for questioning," the president tweeted early Monday. "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!"

He then followed up his latest defense of his immigration order, when in a later tweet Trump said there is "nothing nice about searching for terrorists before they can enter our country. This was a bit part of my campaign. Study the world!"

Protests broke out on Saturday and Sunday at airports across the country with demonstrators urging the government to welcome refugees and immigrants. Several Democratic lawmakers joined the protests at locations in various cities and some Republican lawmakers also expressed concern about the order and its implementation. During a press conference on Sunday, Schumer, holding back tears, called the order "mean-spirited and un-American." He said Democrats are considering legislation to overturn the order.

After the White House initially announced it blocked green card holders from entering the US, the DHS later backtracked and said permanent residents would not be prevented from entering the US.

Overnight, 6 people were killed in a Quebec City mosque in what Canada's prime minister Trudeau dubbed a terrorist attack, one day after the PM tweeted his welcome to anyone around the globe who is "persecuted."
