A major misconception on Capitol Hill right now is the notion that Mick Mulvaney is behind President Trump's decision to back a lawsuit to demolish the Affordable Care Act.

After a week of talking to sources who've discussed the matter privately with Trump, it's clear that this health care push is coming from the president himself. These people say Trump thinks it's a great idea to try to brand the GOP as "the party of health care” by backing the controversial litigation and pushing for legislative change.

Behind the scenes: Trump has privately said he thinks the lawsuit to strike down the Affordable Care Act will probably fail in the courts, according to two sources who discussed the matter with the president last week.
