US President Donald Trump has again denounced his predecessor Barack Obama’s signature domestic achievement — Obamacare — as a “disaster” and vowed to repeal and replace it after the Republican Party passes tax reform.

“ObamaCare premiums are going up, up, up, just as I have been predicting for two years. ObamaCare is OWNED by the Democrats, and it is a disaster,” Trump tweeted on Thursday night. “But do not worry. Even though the Dems want to Obstruct, we will Repeal & Replace right after Tax Cuts!”

Trump’s pledge to repeal Obamacare comes as enrollment in the health-care law has dramatically increased since the start of the open enrollment period. During the first 18 days of the open enrollment period, about 2.3 million Americans signed up for coverage through Obamacare exchanges. This rate of enrollment even did not take place during the same time period under Obama.

Trump has repeatedly called on the Republican Party to repeal and replace Obamacare, but Republicans failed to repeal the law fell short earlier this year. During the last year election campaign, Trump promised to dismantle Obamacare. In October, he signed an executive order he claimed would bring affordable health insurance to millions, taking his first concrete step in dismantling Obamacare.

The order, which tasks the administration with developing policies to increase health-care quality and lower prices, is aimed at letting small businesses band together across the country to buy cheaper, less regulated health plans for their employees.
