Now, he's saying he wasn't kidding.
Speaking to hundreds of "Students for Trump" activists, the president also repeated the racist term "kung flu" he had used most recently at his weekend rally in Tulsa, Oklahoma, and ticked off more nicknames, including "Wuhan" and "Chinese" virus to applause.
White House press secretary Kayleigh McEnnany on Monday defended the "kung flu" phrase, according to the publication. But that was contradicted shortly thereafter.
Trump has only completed three miles of wall where no barrier previously existed, and over 200 miles of new "wall system" - which has been tested and defeated multiple times by power tools, climbers, a magician, and the wind.
"Lost in the coverage is the fact that today less than 6 percent of Americans tested each week are found to have the virus", he said.

FDOH reports over 5,000 new COVID-19 cases on Wednesday
As a public service, Shaw Media will provide open access to information related to the COVID-19 (Coronavirus) emergency. The new cases pushed the state's 7-day rolling average up to nearly 673, an 80-case increase over Tuesday's average .
There is one thing about the deadly pandemic impacting the world which seems to baffle the US President Donald Trump. During a rally in Tulsa, Okla., Trump misleadingly escalated his long-standing claim that the high US case count is simply a result of thorough testing. Discussions were under way about having them in more modest venues or outdoors, perhaps in airplane hangers and amphitheaters, or in smaller cities away from likely protesters.
"So, instead of 25 million tests, let's say we did 10 million tests".
"If someone becomes infected, that's a possibility, if they go out and they put themselves at a behaviour where their behaviour is risky, they're really taking on a responsibility of saying what I'm doing is not that important to my fellow players", said Brian Hainline, chief medical officer for the NCAA, the governing body of USA college sport.
During his presidency, Trump has maintained a hardline stance on immigration and border security, and pushed for a series of controversial measures, including erecting a border wall along the nation's southern border with Mexico, in a bid to deter illegal immigrants.
When the rate of new coronavirus cases began increasing in many US states that had opened bars and restaurants too soon, Vice President Mike Pence blamed it on increased testing.
The increase in state-by-state cases is most pronounced in states which opened first and opened most fully.
