That is such an easy one.
"'The president asked me to look you square in the eyes and to say that he hoped that you voted "no" on this bill so he could run [a primary challenger] against you in 2018, '" the lawmaker quoted Mulvaney as saying, according to the newspaper.
Republican strategist Karl Rove on Thursday criticized the conservative House Freedom Caucus for recently helping sink GOP healthcare legislation.
Despite reports that the House could vote again on the Bill next week, leading congressional officials played down the possibility of a second vote, with senior members of the House Freedom Caucus still opposed to elements of the Bill which they feel constitute a continued use of federal funds to support individual health insurance, an idea to which they are ideologically opposed.
Trump's Twitter post was not impulsive: Bannon and his staff have been closely monitoring the president's tweets and using them as leverage in negotiations.
The caucus contributed to the humiliating failure of the GOP health care bill that would have replaced Barack Obama's Affordable Care Act.
The group's tactics have proven to be too much for some members.
While reacting, Jordan said: "Let's forget the blame and what may happen in the future, let's just do what we said and that's what the Freedom Caucus, and that's what Republicans are committed to".
Where did they come from?
A White House source says the president is sitting back, letting the Freedom Caucus and Tuesday Group work to see if they can find points of agreement before stepping back in.
And with this dynamic in mind, the president has decided his best move is to publicly complain about Freedom Caucus members - repeatedly - and threaten them in advance of the 2018 midterms.
Meanwhile, President Trump tackled another thorny healthcare issue: hosting a listening session on opioid abuse.
Since launching his presidential bid in 2015, Trump has shown little reluctance to assail fellow Republican political adversaries as well as Democrats, often in scathing terms.
The president made opioid abuse a major part of his campaign - particularly in New Hampshire, where more than 400 people died from opioids in 2016.
Trump's attack tweet was an escalation of the fight between him and his party's conservatives who shot back less than an hour later. "And for Amash to reject them is to not reflect what I know to be the desire of the constituents of this district". Addiction is a disease.
Because Trump faces unified opposition by Democratic lawmakers, he can not afford to lose many Republicans as he tries to get his legislative agenda through Congress, including healthcare, tax cuts and infrastructure spending.
