And this is why: "Second, Broadcom's relocation to the US is relevant, too.
The company has been trying to complete a $5.5 billion acquisition of technology firm Brocade Communications Systems since last year, but the deal has been hung up awaiting approval by the Committee on Foreign Investment (CFIUS) in the United States — a government committee that vets foreign investments in US-based companies.
The two firms had initially set a November 1 first deadline to complete the deal, but last month they pushed the deadline back.
Since Broadcom will be a US-based firm itself, it will no longer need approval from CFIUS. And that would hold true for a deal with Qualcomm too.

They're an offshore company looking to buy U.S. assets. But yeah, why would Trump care?
