Two of our White House correspondents report: “Some outsiders see the cascade of hard-line policy ventures, unorthodox appointments and high-level purges of recent days as a sign of Mr. Mulvaney’s expanding influence, assuming that he is pushing Mr. Trump to the right. But insiders call that a misconception, insisting that Mr. Mulvaney at most is pushing on an open door and otherwise is merely liberating Mr. Trump to pursue the courses he prefers.”

Yesterday: Treasury Secretary Steven Mnuchin told lawmakers that White House lawyers had been in touch with his department about a congressional request for Mr. Trump’s tax returns.

Another angle: Attorney General William Barr said on Tuesday that he would release a redacted version of the special counsel’s report “within a week.” He is set to appear before Congress this morning for a second day of testimony.

Bernie Sanders and “Medicare for All”

The senator and early front-runner for the 2020 Democratic presidential nomination plans to reintroduce his Medicare for All Act today, an effort to offer all Americans health insurance under a single plan run by the government and financed by taxpayers.

Mr. Sanders ran for president as an outsider in 2016, but his brand of democratic socialism has taken root on the Democratic left. The co-sponsors of his Medicare for All bill include at least four Senate Democrats who are running against him.

The details: The Times asked a handful of economists and think tanks with a range of perspectives to estimate total health care expenditures in 2019 under a Medicare for All plan. The range of responses, and the things that all the experts agree on, offer a look at what would be the largest domestic policy change in a generation.
