WASHINGTON (AP) — White House economic adviser Larry Kudlow says President Donald Trump won’t back off national security concerns after agreeing to allow U.S. companies to sell some components to Chinese telecommunications giant Huawei (WAH’-way).

Kudlow tells “Fox News Sunday” and CBS’ “Face the Nation” that Huawei will remain on an American blacklist as a potential security threat. He says any additional U.S. licensing “will be for what we call general merchandise, not national security sensitive,” such as chips and software generally available around the world.

Some Republican senators criticized Trump’s announcement Saturday, describing the company as a threat to U.S. national security. In a tweet, Sen. Marco Rubio of Florida called the move a “catastrophic mistake.”

Trump made the comments after meeting with China’s Xi Jinping (shee jihn-peeng) in Japan.
