Meituan Dianping, a Chinese provider of on-demand services, reportedly is in talks to buy bike-sharing company Mobike for around $3.7 billion, according to Chinese newspaper Caixin. Other local media reports say that the price remains subject to change, and that Didi Chuxing and SoftBank are trying to make a last-second play.

Why it matters: Because this isn't really about Meituan Dianping and Mobike, so much as it is about the battle between Tencent (a major holder in both companies) and Alibaba (which backs rival bike-share company Ofo).

It also could be a very quick and cash-rich return for Mobike shareholders, including many in the U.S., which invested around $1 billion in less than two years.

Looking ahead: A Mobike buy could boost Meituan Dianping's top line ahead of its expected IPO, but also could wreak some havoc on its bottom line.

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.
