President Donald Trump lashed out Sunday morning at Democrats who are trying to save the battle-scarred Obamacare medical insurance overhaul, saying they are leaderless, obstructionist and selfish.

'The Democrats, without a leader, have become the party of obstruction,' he tweeted.

'They are only interested in themselves and not in what's best for [the] U.S.'

President Donald Trump blasted Democrats on Sunday morning for standing in the way of a plan to repeal and replace the Obamacare medical insurance law

In a series of tweets, the president called Democrats self-interested, obstructionist and ruderless

Trump appeared to be blasting left-wing politicians for fretting about insurance benefits that might be lost if the Republican-led Congress replaces the current system with something dramatically different.

'You can't compare anything to ObamaCare because ObamaCare is dead,' the president tweeted.

'Dems want billions to go to Insurance Companies to bail out donors....New healthcare plan is on its way. Will have much lower premiums & deductibles while at the same time taking care of pre-existing conditions!'

Trump said Saturday night that Senate Minority Leader Chuck Schumer 'is a poor leader' who is 'leading the Democrats to doom,' but Schumer pushed back Sunday, saying Trump's Obamacare replacement crashed and burned solely because of Republicans' internal divisions

Trump said Saturday night during a Pennsylvania rally that he's growing weary of GOP leaders as they fight among themselves about the finer points of a replacement law.

He told supporters in Harrisburg that his patience is wearing thin.

Singling out two local congressmen, the president warned he would 'be so angry at congressman [Mike] Kelly and congressman [Tom] Marino, and all of our congressmen in this room if we don't get that damn thing passed quickly.'

But 'they'll get it done,' he added. 'We know them. They'll get it done.'

The first Republican repeal-and-replace bill crashed and burned when conservatives in the GOP refused to back it, saying it didn't go far enough.

Speaking of the Obamacare replacement legislation, at Saturday night's rally, Trump said he will be 'so angry ... if we don't get that damn thing passed quickly'

An amended version hit another brick wall on Thursday, and it's unclear how long it will take to arrive at a legislative blueprint that will satisfy both right-wing and centrist Republicans.

While the GOP fiddles, Trump is shifting blame to Democrats.

He said during Saturday's rally that Senate Minority Leader Chuck Schumer is a 'bad leader.'

'He is a poor leader – I've known him a long time – and he's leading the Democrats to doom.'

Schumer pushed back the following morning on 'Fox News Sunday,' saying that the failure 'wasn't the Democrats. He tries to blame the Democrats, but he didn't need a single Democratic vote to pass it in the house.'

'He couldn't do it. He couldn't do it twice. He ought to realize that they ought to back off repealing Obamacare.'
