As Donald Trump himself tweeted on Monday morning...

Busy week planned with a heavy focus on jobs and national security. Top executives coming in at 9:00 A.M. to talk manufacturing in America. — Donald J. Trump (@realDonaldTrump) January 23, 2017

... the president's first official day on the job will be busy, including a meeting with business executivesm congressional leaders (including a separate meeting with House Speaker Paul Ryan), signing executive orders and getting his cabinet picks voted through.

According to the WSJ, Trump is also expected to sign various executive orders around 10:30am, which as previewed yesterday will include such topics as trade, immigration, government hiring, Obamacare and a lobbying ban.

According to the White House, which released daily guidance for the president on Sunday evening, Trump's Monday will include a “breakfast and listening session with key business leaders” and a similar afternoon session with union leaders and “American Workers.”

Among this week's key meetings, Trump is scheduled to with meet "top executives" at 9 a.m. today to discuss manufacturing, and British PM Theresa May on Friday.

He’ll have lunch with Vice President Mike Pence at noon. At 5 p.m., Trump is scheduled to hold a leadership reception with congressional leaders from both parties, followed by a private meeting with House Speaker Paul Ryan an hour later.

But the media will likely be fascinating by White House press secretary Sean Spicer, who will deliver an on-camera briefing at 1 p.m. that’s sure to be a focus of the day, given the weekend focus on the Trump administrations reaction to media coverage of the crowd sizes at the inauguration.

Also expect a series of cabinet votes: Mike Pompeo, the new head of the CIA, should get a vote today. White House officials expect at least three more Cabinet nominees, Ben Carson, Nikki Haley and Rick Perry, to be voted on by the end of the week, per the WSJ. And while Tillerson may not get a vote this week, Graham and McCain are now on board.

Clearing Mr. Trump’s nominees is a top priority because he is starting his presidency with a much thinner cabinet than his predecessor. On Barack Obama’s first day in office in 2009, the Senate approved six members of his cabinet. A seventh, Defense Secretary Bob Gates, was a holdover from the George W. Bush administration. The Senate that day confirmed an eighth nominee, Peter Orszag, to lead the Office of Management and Budget.

Cited by the WSJ, Trump is optimistic about the beginning of his presidency despite a rocky first weekend that saw mass anti-Trump protests across the nation and world and his representatives’ repeated falsehoods about media reporting of verifiable events.
