Didi Chuxing, the Chinese ride-hailing giant that acquired Uber's local business last year, has opened a research center in Silicon Valley, the company said on Wednesday.

Focused on artificial intelligence, security, and autonomous driving, the office will be in Mountain View—Google's hometown—and it has hired Charlie Miller, the famed car hacker who left Uber last week. Didi Chuxing VP of Research Institute Dr. Fengmin Gong will lead the lab.

Joining the race: Despite being one of the biggest ride-hailing companies in the world, Didi seems to be joining the race to build self-driving cars a bit later than everyone else, though it's impossible to know how long it's been working on this tech behind closed doors. On Wednesday, it also announced it's co-hosting a competition with online learning company Udacity, which offers education on self-driving car technology, and the winners will get to work with Didi.

CPAC Republicans choose conservatism over constituents

CPAC proved such a draw, conservative Republicans chose the conference over their constituents.

Why it matters: More than a dozen House Republicans voted by proxy on the $1.9 trillion COVID-19 relief bill in Washington so they could speak at the Conservative Political Action Conference, known as CPAC. And Sen. Ted Cruz skipped an Air Force One flight as President Biden flew to Cruz's hometown of Houston to survey storm damage.

Border Democrat warns Biden about immigrant fallout

A Democratic lawmaker representing a border district warned the Biden administration against easing up too much on unauthorized immigrants, citing their impact on his constituents, local hospitals and their potential to spread the coronavirus.

Why it matters: Rep. Henry Cuellar (D-Texas) told Axios he supports President Biden. But the moderate said he sees the downsides of efforts to placate pro-immigrant groups, an effort that threatens to blow up on the administration.

In CPAC speech, Trump says he won't start a 3rd party

In his first public speech since leaving office, former President Trump told the audience at the Conservative Political Action Conference (CPAC) that he would not start a third party because "we have the Republican party."

Why it matters: The former president aims to cement himself as Republicans' "presumptive 2024 nominee" as his top contenders — including former members of his administration — face the challenge of running against the GOP's most popular politician.
