Sen. Tom Cotton (R-Ark.) suggestion that Chinese students should not be allowed to study science and technology in the United States has set off a debate about espionage and immigration.

What's happening: Under the Trump administration, the DOJ's China Initiative has targeted intellectual property theft at America's research institutions.

  • Chinese students studying in some sensitive fields already face new visa restrictions.
  • Cotton's suggestion on April 26 takes those measures one step further, proposing that any science-related topic should be entirely off-limits for Chinese students, because they could return to China and “design weapons and other devices that can be used against the American people,” he said.

Context: The number of Chinese international students at U.S. universities has nearly tripled over the past decade, and they comprise the largest percentage of the U.S. international student population.

Related: A recent report from the JASON program at MITRE Corp. found existing ethics and disclosure practices could both preserve and protect the openness of the U.S. research system, my Axios colleagues Alison Snyder and Erica Pandey reported earlier this year.

Editor's note: This story has been corrected to reflect the China Initiative is part of DOJ not FBI.

China says U.S. is "endangering peace" with high-level visit to Taiwan

Health and Human Services Secretary Alex Azar announced Tuesday night he will lead a delegation to Taiwan "in the coming days."

Why it matters: It's the highest-level visit by a U.S. cabinet official to Taiwan since 1979. Azar is also the first U.S. Cabinet member to visit the island state in six years. The visit has angered China, which views Taiwan as part of its territory. Chinese officials accused the U.S. Wednesday of "endangering peace" with the visit, AFP reports.

Schumer pushes for doomed filibuster changes

Senate Majority Leader Chuck Schumer told the Democratic caucus Tuesday night he plans to propose instituting a one-time "talking" filibuster requirement, and bypassing the 60-vote threshold for major legislation, to pass the party's election reforms package via simple majority.

Why it matters: While Schumer acknowledged both votes are expected to fail — and some vulnerable Democrats up for re-election feel it will put them in a tough spot — he argued it's worth putting members on the record for historic legislation.
