President Donald Trump seized on the chaos of Monday evening’s Iowa caucuses to attack Democrats, describing the delay of the results as an “unmitigated disaster” and proclaiming himself the only winner.

“The Democrat Caucus is an unmitigated disaster,” Trump tweeted early Tuesday. “Nothing works, just like they ran the Country. Remember the 5 Billion Dollar Obamacare Website, that should have cost 2% of that. The only person that can claim a very big victory in Iowa last night is ‘Trump.'”

The results of the caucuses were still unknown well into Tuesday morning amid problems with an app designed to transmit voter data to the Iowa Democratic Party.

Late Monday, Trump claimed a "big WIN for us in Iowa tonight," adding, "Thank you!"

Iowa Democratic officials have blamed the problems on an app that was being used to report results. The exact nature of the problems is unclear, though officials have said the system was not hacked.

The "Obamacare website" Trump mentioned in his tweet was the one used to purchase health insurance on the exchanges established by the Affordable Care Act. Its 2013 debut was plagued with technical issues, though the highest estimates of the website's development cost, at about $2 billion, are less than half the figure Trump cited.
