(CNN) As people of Hawaii catch their breath following the jarring missile alert mishap over the weekend, scrutiny has reached the White House and how it grappled with the mistaken alarm.

A message went out to the people of Hawaii on Saturday, telling them to seek shelter due to an incoming ballistic missile threat. State leaders and emergency officials said after that the alert was a false alarm, with the state's governor saying it was because an employee "pushed the wrong button."

President Donald Trump was quiet about the incident in its wake, and on Sunday night he said he was glad Hawaiian officials had taken responsibility for the massive failure of the statewide system.

The following timeline of events related to the false missile warning in Hawaii reflects the President's whereabouts during the key time frame.

They promote the Fake Book of a mentally deranged author, who knowingly writes false information. The Mainstream Media is crazed that WE won the election!"

Evening -- President Trump has dinner with former New York Mayor Rudy Giuliani at Mar-a-Lago, a person who was there said. They both pause during the meal as a singer performed "God Bless America." Giuliani is walking with a cane.

7:20 p.m. ET -- Trump makes his first comments about the false alarm alerts as he walks to dinner with House Majority Leader Kevin McCarthy at his West Palm golf club: "Well, that was a state thing. But we're going to now get involved with them. I love that they took responsibility. They took total responsibility. But we're going to get involved. Their attitude and their -- what they want to do, I think it's terrific. They took responsibility. They made a mistake."

Asked whether he would make sure it won't happen again, Trump said: "Well, we hope it won't happen again. But part of it is that people are on edge, but maybe, eventually, we'll solve the problem so they won't have to be so on edge."
