WILLIAM BRANGHAM: In the day's other headlines: California Governor Gavin Newsom says the Trump administration is using the Justice Department to investigate him and his wife, saying the move is politically motivated.

GOV.

GAVIN NEWSOM (D-CA): Donald Trump isn't just coming after me because of my mean tweets.

He's coming after me because I'm considering running for president, because he hates that I have consistently called him out over and over again for his lies and deceit.

WILLIAM BRANGHAM: Newsom says that, in recent days, federal agents have knocked on the doors of friends and former employees looking for records of an unspecified crime.

The Democrat also likened himself to former FBI Director James Comey and other Trump foes who have been targeted by the DOJ.

But a source tells the "News Hour" that there are at least two ongoing probes into those close to Newsom which originated with prosecutors in California, not in Washington, D.C.

The U.S.

military says a B-52 Stratofortress bomber crashed shortly after takeoff in California's Mojave Desert today.

Officials at the base wrote on social media that -- quote -- "Emergency crews immediately responded to the scene and the situation is ongoing."

There was no immediate word on whether anyone was hurt.

The B-52 is typically crewed by five people and is a long-range bomber that first entered service in the 1950s.

In Missouri, federal investigators were on the scene today of a plane crash that killed 12 people, including the pilot.

Authorities say the plane was taking off for a skydiving trip yesterday when it went down soon after takeoff in Butler, Missouri, which is about 70 miles south of Kansas City.

A local official says the pilot may have been trying to reach a nearby road when the aircraft stalled and crashed.

The company that operates the plane says the local skydiving community is in shock.

MAKSYM OSTAPENKO, Director General, (through translator): This is one of the most renowned examples of Ukraine's cultural and historical heritage that Russia is targeting precisely to destroy it.

WILLIAM BRANGHAM: Also today, Ukraine formally opened the first phase of membership talks with the European Union.
