The tweet, posted at 9:55 a.m. ET, came after NBC News broke a story that Trump had asked for a "nearly tenfold increase in the US nuclear arsenal" at the same July 20 meeting where Secretary of State Rex Tillerson reportedly called Trump a "moron".
Last week, NBC News reported that after the meeting took place, Secretary of State Rex Tillerson remarked that the president was a "moron".
Further, NBC reported on Wednesday, it was after that meeting officials heard Tillerson say Trump is a "moron", a comment Tillerson and the White House has denied making.
Huckabee's comments came hours after Trump tweeted: "Why isn't the Senate Intel Committee looking into the Fake News Networks in OUR country tos ee why so much of our news is just made up-FAKE!"
Trump called the report "pure fiction" on Twitter.
The report comes as Trump is preparing for an 11-day trip to Asia, where he will seek to bolster worldwide support to pressure North Korea to curb its nuclear and ballistic missile weapons testing. U.S. Rep. Diana DeGette, of Denver, said Trump's suggestion was very bad for the country.
Trump again called the report "fake news" and added that such an increase in the nuclear arsenal was "totally unnecessary". I want them in ideal condition, flawless shape. The most recent nuclear-posture review came in 2010 under President Barack Obama with the express goal of reducing weapons stockpiles.
NBC owns and operates stations in major markets including New York City; Los Angeles; Chicago; San Francisco; Philadelphia; Washington, D.C.; Miami; Dallas; and Boston. Instead, licenses are issued to local stations. Trump said his administration would "look at breaking that deal up", but hasn't followed through on the threat.
As a businessman and candidate, Trump frequently threatened to sue news organizations over unflattering coverage.
