Trump May End Government Shutdown Because 'It's Always About His Vanity,' Says 'Art of the Deal' Co-Author

President Donald Trump may end the ongoing partial government shutdown because of his vanity, the co-author of his book The Art of the Deal has suggested.

Tony Schwartz, who helped pen the 1987 biography, wrote on his Twitter profile that Trump was very eager to deliver the State of the Union scheduled for January 29 to Congress. House Speaker Nancy Pelosi requested the president delay the speech due to the shutdown.

"There is one reason I can imagine Trump finding a way to open the government by January 29," Schwartz tweeted. "He desperately wants to give the State of the Union to Congress. It's always, always about his vanity." The political impasse continues over Trump's demand for $5.7 billion to help build a U.S.-Mexico border wall, a key promise of his 2016 election campaign.

White House press secretary Sarah Huckabee Sanders said this week that plans were still in motion for the State of the Union to go ahead—despite appeals from Representative Pelosi.

"Nancy Pelosi made an invitation to the President on the State of the Union, he accepted, she cited security concerns as a potential reason to delay it, those concerns were addressed by the Department of Homeland Security and the United States Secret Service," Sanders told the media earlier this week, as reported by CNN. "At this point, we're moving forward," she added.

Most of the Schwartz's recent social media feed is made up of analyses of Trump's actions. Today, the author offered another summary of the president's current situation.

"One key to Trump is that he has no core beliefs or deeply held values," Schwartz wrote. "His wall was just a way to get elected. He holds on tenaciously to avoid feeling humiliated by Dems & criticized by his base. He is a prisoner to his neediness, with no true north to guide him."

Last Wednesday, Pelosi sent a letter to the president, asking for the State of the Union to be put aside until the government fully re-opens. It has been partially closed for over a month.

"Given the security concerns...I suggest that we work together to determine another suitable date after government has re-opened for this address or for you to consider delivering your State of the Union address in writing to the Congress," the politician wrote at the time.

The Associated Press reported yesterday that officials have been mulling over alternative venues for the address, which is typically given in front of a joint session of Congress.

One new option considered was a rally style event, but little has been confirmed, the outlet noted. In the meantime, hundreds of thousands of federal workers remain without paychecks.

Secretary of Homeland Security, Kirstjen Nielsen, tweeted on January 16 that the agency was "fully prepared to support and secure the State of the Union" if it goes ahead. Today, Trump wrote on his own profile: "BUILD A WALL & CRIME WILL FALL!"
