WASHINGTON (Reuters) - After Republicans’ effort to pass a healthcare bill in the Senate collapsed on Monday, U.S. President Donald Trump on Tuesday put the blame on Democrats and a few members of his own party, but vowed to come back with “a great healthcare plan.” “We were let down by all of the Democrats and a few Republicans. Most Republicans were loyal, terrific & worked really hard. We will return!” Trump wrote on Twitter. “As I have always said, let ObamaCare fail and then come together and do a great healthcare plan. Stay tuned!” Trump added.
