Billionaire investor Carl Icahn is denying that he knew about President Trump's steel tariff plan before it was formally disclosed.

Why it matters: Icahn sold at least part of his stake in The Manitowoc Co., which relies heavily on steel, ahead of Trump's announcement last Thursday. The stock has since fallen more than 5%, but Icahn — who once served as an unpaid economic advisor to Trump — had declined comment until today.

Icahn's statement:

"Any suggestion that we had prior knowledge of the Trump administration’s announcement of new tariffs on steel imports is categorically untrue. We reduced our position in Manitowoc for legitimate investment reasons having nothing to do with that announcement.”

What we still don't know: If Icahn has sold more Manitowoc shares since his initial disclosure, and what those "legitimate investment reasons" were.

The National Association of Letter Carriers, the union representing roughly 300,000 current and former postal workers, on Friday endorsed Joe Biden in the 2020 presidential election, calling him "a fierce ally and defender of the U.S. Postal Service," reports NBC News.

Why it matters: The endorsement comes as President Trump has vowed to block additional funding for the USPS in the next coronavirus stimulus package, linking it to his continued baseless claims that increased mail-in voting will lead to widespread voter fraud.

U.S. lawmakers are demanding answers from the World Bank about its continued operation of a $50 million loan program in Xinjiang, following Axios reporting on the loans.

Why it matters: The Chinese government is currently waging a campaign of cultural and demographic genocide against ethnic minorities in Xinjiang, in northwest China. The lawmakers contend that the recipients of the loans may be complicit in that repression.
