The U.S. Department of Justice is suing to block Hewlett Packard Enterprise's $14 billion acquisition of Juniper Networks, arguing that it could hinder competition and impede innovation. According to the DOJ, if the deal goes through, only two companies - Cisco Systems and HPE - would control over 70% of the U.S. networking equipment market. This lawsuit is the first antitrust action during the Trump administration, coming just 10 days after Donald Trump's inauguration. Concerns were raised at HPE about Juniper, with reports of a former executive allegedly urging his team to 'kill Juniper' in sales competitions.
