US President Donald Trump on Tuesday outlined an executive order aimed at strengthening the cybersecurity of government and private-sector computer networks.
Both Trump and his spokesman Sean Spicer indicated Trump would sign the executive order, but the White House later said the signing was "cancelled for today," with no explanation given.
Trump told a meeting at the White House that the order would hold his cabinet secretaries and agency heads accountable for the cybersecurity of their organizations, which he said were currently inadequately protected from hacking attacks.
"We must protect federal networks and data. We operate these networks on behalf of the American people and they are very important," Trump said at the White House after a "listening session" with cybersecurity specialists.
The order follows serious hacking incidents last year that the CIA later concluded was part of an effort by Russia to meddle in the presidential election.
Trump was sceptical of any Russian involvement, and Moscow denied it carried out the hacks, which allowed damaging information to be leaked to the press from the Democratic National Committee.
Trump said Tuesday that hack was a good example of the vulnerabilities that exist.
The president said despite spending more than the Republican National Committee on cybersecurity, the party's executive committee was "hacked successfully, very successfully, and terribly successfully."
Trump said there was an attempt during the election campaign to hack the Republican National Committee during the election, but it failed.
