Canada issues travel advisory for those with "X" gender marker on passport

Catch up quick: On the first day of his second term, Trump signed an executive order mandating that the federal government recognize only male and female as the two biological sexes.

• Following Trump's order, the State Department suspended applications for passports requesting to change their sex marker or request a "X" identifier.
• U.S. District Judge Julia Kobick blocked the order in June, allowing nonbinary Americans the ability to receive passports with an "X" designation.
• The administration asked the Supreme Court last week to pause the ruling.
• Solicitor General D. John Sauer argued Kobick's decision "injures the United States by compelling it to speak to foreign governments in contravention of both the President's foreign policy and scientific reality."

State of play: Canada has offered the "X" identifier since 2017.

• It joins several other countries in Europe that recently issued travel advisories citing risks for people with "X" passports and stricter U.S. detention and deportation laws.
• The Canadian advisory also warns that within some countries people "may still be asked to provide your sex/gender information as either male or female."

What they're saying: The Department of State and Customs and Border Protection did not respond to Axios' request for comment in time for publication.

• Jennifer Young, spokeswoman for the U.S. Embassy in Canada, said the embassy is "not in a position to provide comment or schedule interviews at the time," because of the current government shutdown.

What's next: The Supreme Court will decide if the Trump administration can enforce its two-sex passport rule while legal challenges continue.
