Several Wounded in Shooting at YouTube Headquarters; Police Say Female Suspect Is Dead

A woman opened fire at YouTube’s headquarters in San Bruno, California, on Tuesday afternoon, shooting three people — one of whom was critically injured — before killing herself, the authorities said. The motivation for the shooting and the name of the woman were not known Tuesday evening. The local and state police, aided by several federal agencies, were investigating. The police said the woman had used a handgun in the attack, but would not say if she was a YouTube employee. Silicon Valley’s offices have been remarkably safe and open places, despite routine threats.

In Texas, Cruz Is Facing an Unusual Challenge: A Formidably Financed Democrat

Sen. Ted Cruz, R-Texas, kicked off his re-election campaign this week with a new Texas-themed slogan and a new video, but something else that was entirely new went largely unspoken — a formidable and well-funded Democratic opponent. For the first time in Cruz’s rise to political prominence in Texas, he is facing a serious Democratic challenger, Rep. Beto O’Rourke from El Paso, who has stunned political observers by raising more money than any Democrat who has ever run for a Senate seat in Texas. O’Rourke, a former punk-rock bassist and El Paso city councilman, has raised $13.2 million.

Trump Plans to Send National Guard to Mexican Border

The White House said Tuesday night that President Donald Trump planned to deploy the National Guard to the southern border to confront what it called a growing threat of immigrants, drugs and crime from Central America after the president for the third consecutive day warned about the looming dangers of unchecked immigration. Trump’s advisers said Monday that he was readying new legislation to block migrants and asylum-seekers from entering the United States. But in remarks on Tuesday that caught some of his top advisers by surprise, he suggested the more dramatic approach of sending in the military.

Ex-Skadden Lawyer Is Sentenced to 30 Days in Russia Inquiry

A former lawyer for a powerful international corporate law firm was sentenced Tuesday to 30 days in prison for lying to investigators in the special counsel inquiry about his communications with a Trump campaign aide and a Ukrainian businessman believed to be a Russian intelligence operative. The former lawyer, Alex van der Zwaan was also fined $20,000. Van der Zwaan admitted he deceived investigators who interviewed him in November as part of their examination of contacts between the Ukrainian and two former high-ranking Trump campaign officials: Paul Manafort, once Donald Trump’s campaign chairman, and Rick Gates, Trump’s deputy campaign manager.

Cities and States Mount Court Challenge to Census Question on Citizenship

A largely Democratic coalition of 17 state attorneys general and seven cities filed a lawsuit Tuesday to block the Trump administration from asking respondents to the 2020 census whether they are citizens, opening a constitutional battle that some experts believe is destined to be settled by the Supreme Court. In the lawsuit, filed in U.S. District Court in New York, the officials argued that adding the question would depress the response to the census by noncitizens, thwarting the Constitution’s requirement of an “actual enumeration” of the nation’s residents. The suit also claimed that the decision violated federal administrative law.

The Final Obamacare Tally Is In. About 400,000 Fewer People Signed Up This Year.

The Trump administration said Tuesday that 11.8 million people had signed up for health insurance through the Affordable Care Act marketplaces for 2018 — roughly 400,000 fewer than last year. The drop was relatively small, given that President Donald Trump had sharply cut federal outreach efforts and the open enrollment period was half as long as in past years. Virtually the entire decrease came in the 39 states that use the marketplace run by the federal government, HealthCare.gov. In the 11 states that sell coverage for the Affordable Care Act through their own marketplaces, enrollment remained the same.

Cosby Jury to Hear Account That His Accuser Was Scheming

In a major victory for Bill Cosby, the judge in his sexual assault trial ruled Tuesday to admit testimony from a Temple University academic adviser who says that Cosby’s central accuser, Andrea Constand, told her she could make money by falsely claiming that she had been molested by a prominent person. Judge Steven T. O’Neill of the Montgomery County Court of Common Pleas had barred the testimony of the administrator, Marguerite Jackson, 56, during Cosby’s first trial, which ended with a hung jury last summer. Constand testified in the first trial that she did not know Jackson.
