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."

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.
