The US government has called for an investigation of Broadcom's proposed acquisition of rival chipmaker Qualcomm, worrying the hostile bid could pose a risk to US national security.

The objection was raised by the Committee on Foreign Investment in the United States, a government panel that reviews mergers that could result in a foreign company controlling an American business. The panel, also known as Cfius, is specifically concerned with Broadcom's relationships with foreign entities, worrying the deal could weaken "Qualcomm's technological leadership," according to a letter from a United States Treasury official.
