The Committee on Foreign Investment in the United States is an inter-agency committee authorized to review transactions that could result in the control of a US business by a foreign person in order to determine the effect of the transaction on the security of the US. Over the last few years, CIFUS has been in the process of reforming. On 13 June 2017, US Secretary of Defense James Mattis, described CFIUS as "outdated," saying it "needs to be updated to deal with today's situation." When asked for suggested changes to CFIUS, Secretary Mattis offered as one example "the lack of restrictions on investment in certain types of technologies that we must have put in place." He declined to specify in the open session which technologies he would seek to protect.
