Americans in six states are voting today in the Democratic primaries after Super Tuesday results narrowed the field to former Vice President Joe Biden, Sen. Bernie Sanders (I-Vt.) and Rep. Tulsi Gabbard (D-Hawaii).

The state of play: The coronavirus looms over the primaries as campaign workers and polling places try to protect themselves with gloves and hand sanitizer. Michigan, Mississippi, Missouri, Idaho, North Dakota and Washington will have closed their polls by 11 p.m. ET.

Democrats called on President Trump to disclose his tax returns following a New York Times report alleging he paid $750 in federal income taxes in 2016 and 2017 and nothing in 10 of the past 15 years.

Details: Trump said the report was "total fake news," that he's unable to release the returns as they're "under audit" by the IRS, "which does not treat me well." House Speaker Nancy Pelosi (D-Calif.) said in a statement the report "provides further evidence of the clear need" for a House lawsuit to access the tax returns and "ensure the presidential audit program is functioning effectively, without improper influence."

Firefighters in the western U.S. were facing "critical fire weather conditions," as a rapidly spreading new wildfire in Northern California prompted fresh evacuations Sunday.

Why it matters: Wildfires have burned a record 3.6 million acres in California this year, killing 26 people and razing over 7,600 structures, per Cal Fire. Utility provider Pacific Gas & Electric cut power to 11,000 customers early Sunday and planned outages for 54,000 others later in the day because of fire risks.
