President Donald Trump on Monday issued an order blocking Broadcom's proposed $117 billion acquisition of rival chipmaker Qualcomm, saying the deal threatened to "impair the national security" of the US.

"The proposed takeover of Qualcomm by the Purchaser is prohibited, and any substantially equivalent merger, acquisition, or takeover, whether effected directly or indirectly, is also prohibited," Trump wrote in an order, which directs both companies to immediately abandon the proposed deal.
