Chinese Huawei executive charged with espionage in Poland

A local sales director for the Chinese company Huawei Technologies, identified by people familiar as Weijing Wang, has been charged with high-level espionage on China's behalf in Poland, the Wall Street Journal reports.

Why it matters: The charge bolsters U.S. and other Western nations' suspicions that Huawei's technology could be used by China to spy on other nations. Last month, the company's chief financial officer was detained in Canada for allegedly violating U.S. sanctions on Iran.

House committees leading the impeachment inquiry against President Trump subpoenaed acting White House chief of staff Mick Mulvaney on Friday.

The big picture: This comes after nearly a month of White House refusals to comply with House investigations into whether Trump jeopardized national security by pressing Ukraine to interfere in the 2020 presidential election, and by withholding security assistance provided by Congress to help Ukraine, per the subpoena. The committees are demanding documents by Oct. 18.

Sen. Ron Johnson (R.-Wis.) told the Wall Street Journal that he learned of a possible quid pro quo between the Trump administration and Ukraine's government from EU Ambassador Gordon Sondland.

The big picture: Johnson said that he pressed President Trump on the issue, which allegedly linked the distribution of $400 million in U.S. military aid with a Ukrainian investigation of former Vice President Joe Biden, in an Aug. 31 phone call. "He said ... 'No way. I would never do that. Who told you that?'" Johnson told the Journal of his conversation with the president.
