WASHINGTON (AP) — As if spotting a mirage in the southwestern desert, President Donald Trump and his aides are seeing a wall standing along the Mexico border where none exists.

For months Trump has claimed that wall construction is underway and he's brought the matter to the forefront again as the White House presses lawmakers to free up money for what the president calls the "remaining sections."

That's like toeing the starting line and contemplating the remaining miles of a marathon.

In an argumentative Oval Office meeting Tuesday, Democratic leaders joined Trump in exaggerating the consequences of a partial government shutdown if a budget deal is not reached by Dec. 21. A look at some of the claims as Washington searched for that deal, with a border wall at the center of contention.

WHAT'S NEW?

TRUMP: "Tremendous amounts of wall have already been built." — statement in meeting with the House Democratic leader, Nancy Pelosi, and the Senate Democratic leader, Chuck Schumer.

TRUMP: "People do not yet realize how much of the Wall, including really effective renovation, has already been built." ''We have already built large new sections & fully renovated others, making them like new." — tweets.

THE FACTS: Tremendous portions of the wall have not been built. Yes, some barrier renovation has happened but little wall construction has been completed under Trump.

Congress allocated about $1.4 billion in the spring — a bit more than 5 percent of what Trump wanted — for border security and specified that the money was not to be used for construction of the prototype wall sections that stand near San Diego. Instead, the money is to strengthen or replace existing fencing with more secure fencing.

Altogether, Trump promised in the campaign that he'd build a 1,000-mile (1,600 kilometer) wall, as high as 40 feet or 12 meters (and have Mexico pay for it, which isn't happening). If some 650 miles (1,050 km) of existing fencing are considered in the equation, that leaves him with about 350 miles (560 km) of wall to build.

WHAT'S A WALL?

KELLYANNE CONWAY, Trump adviser: "You just want to keep saying 'wall, wall, wall.' ... There are many ways to secure a border." — to reporters asking Tuesday about Trump's wall.

THE FACTS: Trump, of course, has been saying wall, wall, wall, since the 2015 Republican primaries, in a torrent of tweets and in countless rallies. Or, as he put it in Tuesday's tweet, "the Wall." He's described the material, the dimensions and the beauty of it, and had prototype sections built, and they are of a wall, not a fence.

Federal officials — and Trump himself, at times — have tried to scale back expectations by noting, for example, that "there are places where you can't have a physical wall," as Conway put it Tuesday. "There are rivers. There's brush." But Trump already accounted for that when he promised 1,000 miles of wall to supplement another 1,000 miles of rivers and other natural barriers.

"The Wall is the Wall, it has never changed or evolved from the first day I conceived of it," he tweeted in January, as if inviting voters to hold him to his literal promise.

TRUMP: "If we don't get what we want one way or another ... I will shut down the government." — in meeting with Pelosi and Schumer.

SCHUMER, asked after the meeting what happens if Trump doesn't compromise: "He will get no wall and he will get a shutdown."

PELOSI: A "Trump shutdown" could be his "holiday president to the American people."

THE FACTS: Everyone's exaggerating. The government is not at risk of closing if a deal is not reached by Dec. 21.

About three-quarters of the government will continue to have enough money to operate. But even a partial shutdown could be disruptive. Among the affected departments absent a deal: Homeland Security, Transportation, Agriculture, State, Justice.

Congress has approved continued financing of the Defense and Veterans Affairs departments, among other federal operations, and workers deemed essential would not be idled.
