President Donald Trump stepped up his criticism of Senate Majority Leader Mitch McConnell on Thursday for not muscling through a health-care bill, escalating an extraordinary fight with a key leader of his own party.

“Can you believe that Mitch McConnell, who has screamed Repeal & Replace for 7 years, couldn’t get it done,” Trump wrote on Twitter. “Must Repeal & Replace ObamaCare!”

Trump’s morning tweet was his second in 24 hours targeting McConnell for remarks the Kentucky Republican made earlier in the week suggesting that Trump’s lack of political experience had led to “excessive expectations” for passing major legislation.
