WASHINGTON — Impetuous and instinctive, convinced of broad but hidden plots to undermine him, eager to fight and prone to what an aide called “alternative facts,” President Trump has shown in just days in office that he is like few if any occupants of the White House before him.
He sits in the White House at night, watching television or reading social media, and through Twitter issues instant judgments on what he sees. He channels fringe ideas and gives them as much weight as carefully researched reports. He denigrates the conclusions of intelligence professionals and then later denies having done so. He thrives on conflict and chaos.
For a capital that typically struggles to adjust to the ways of a new president every four or eight years, Mr. Trump has posed a singular challenge. Rarely if ever has a president been as reactive to random inputs as Mr. Trump. Career government officials and members of Congress alike are left to discern policy from random tweets spurred by whatever happened to be on television when the president grabbed the remote control.
While that habit generated conversation and consternation when Mr. Trump was a candidate, he now serves as commander in chief and his 140-character pronouncements carry the power of an Olympian lightning bolt. In the last 24 hours alone, he threatened to send federal forces into Chicago and vowed to investigate his own false claim that three million to five million votes were cast illegally in November, costing him the popular vote. The trumpet blasts came even as he issues daily executive actions overturning longstanding policies across the board.
Mr. Trump’s advisers say that his frenzied if admittedly impulsive approach appeals to voters because it shows that he is a man of action. Those complaining about his fixation with fictional vote fraud or crowd counts at his inauguration, in their view, are simply seeking ways to undercut his legitimacy.
Yet some of his own advisers also privately worry about his penchant for picking unnecessary fights and drifting off message. They talk about taking away his telephone or canceling his Twitter account, only to be dismissed by a president intent on keeping his own outlets to the world.
The results play out daily. During his 8 p.m. show on Fox News on Tuesday, Bill O’Reilly aired a segment on the crime crisis in Chicago and interviewed an expert talking about whether the president could intervene. The guest called the violence in Chicago “carnage.”
At 9:25 p.m., Mr. Trump sent out a tweet, using the same statistics that Mr. O’Reilly had flashed on the screen. “If Chicago doesn’t fix the horrible ‘carnage’ going on, 228 shootings in 2017 with 42 killings (up 24% from 2016), I will send in the Feds!” the president wrote.
After reporters pressed Sean Spicer, the White House press secretary, on Tuesday about why, if he really believed there was widespread vote fraud, the president did not order an investigation, Mr. Trump on Wednesday morning blasted out a tweet saying he would do just that.
More than any president before him, Mr. Trump is a creature of television and social media, a reality show star obsessed with Nielsen ratings who vaulted himself to the highest office in the land on the back of a robust Twitter account.
President Lyndon B. Johnson kept three televisions in the Oval Office so he could watch all three network nightly news broadcasts at the same time. But with the advent of the 24-hour cable television era, other presidents have made a point of shielding themselves from the nonstop chatter to avoid becoming too reactive.
President George W. Bush always said he avoided watching television news. (“Sorry,” he would tell television correspondents with a sheepish grin.) Mr. Obama opted instead for ESPN’s “SportsCenter” late at night.
Mr. Trump, on the other hand, while not much of a reader, is a voracious consumer of broadcast and social media, and it clearly guides his actions. Examples abound.
One morning in November after the election as he was preparing to become president, Fox News aired a segment at 6:25 a.m. on college students burning the American flag. At 6:55 a.m., Mr. Trump tweeted: “Nobody should be allowed to burn the American flag – if they do, there must be consequences – perhaps loss of citizenship or year in jail!”
Similarly, posts about the high cost of a new Air Force One and the F-35 fighter jet came soon after news reports rather than policy briefings.
So far at least, Mr. Trump has shown that he does not believe in the restraints other presidents put on themselves. After the Dow Jones industrial average surpassed the 20,000 mark on Wednesday, Mr. Trump’s staff-managed official Twitter account sent out a message declaring it “Great!” even though other presidents made it a policy not to comment on daily market gyrations.
The Chicago declaration provided a case in point. A threat to send federal forces into one of the nation’s largest cities – Mr. Trump did not specify whether he meant the National Guard, the Federal Bureau of Investigation or any other agency – is usually not one issued lightly. During Hurricane Katrina, Mr. Bush spent crucial days privately debating with aides whether to take over the National Guard in Louisiana.
Mr. Trump sees little need for such deliberations before weighing in. This is, as he put it in his Inaugural Address, “the hour of action.” Whether the action will now follow the words remains uncertain less than a week into his presidency.
