[8] Congress enacted the IEEPA in 1977 to clarify and restrict presidential power during times of declared national emergency under the Trading with the Enemy Act of 1917 ("TWEA").
Under TWEA, starting with Franklin D. Roosevelt in 1933, presidents had the power to declare emergencies without limiting their scope or duration, without citing the relevant statutes, and without congressional oversight.
[14] In 1988, Congress passed amendments to the TWEA and IEEPA, authored by Rep. Howard Berman (D–CA), aimed at protecting the rights of American citizens to receive information, regardless of the country of origin of such materials used, by exempting varied methods of communication from regulation.
"[16] In response, the Berman-sponsored Free Trade in Ideas Act—passed by Congress in 1994—revised the original amendment's First Amendment exemptions to include newer and forthcoming mediums (including intangible items such as television broadcasts and methods of personal communication), further clarifying that the President's emergency sanction powers under the IEEPA and TWEA cannot be used with regard to any information or informational materials, regardless of their format or medium, or whether they are intended for personal or commercial use.
[19] Executing these blocking actions led to a series of legal cases challenging federal authority to indefinitely prevent charitable organizations from accessing their assets held in the United States.
[16] On May 30, 2019, the White House announced that Trump would use IEEPA powers to introduce tariffs on Mexican exports in response to the national security threat of illegal immigration from Mexico into the United States.
Critics considered the order an effort to intimidate ICC civil servants from proceeding with its investigation and accused the administration of targeting the two prosecutors, both of African origin, based on their race.
[27][28] Observers (including Trump administration critics and many TikTok users) raised First Amendment concerns with the executive order and suggested that, while national security concerns were cited to justify them, the sanctions were prompted by the administration's hostile relations toward China in general and retaliation against TikTok in particular for certain anti-Trump content hosted by the app and, as also suggested by ByteDance in court documents pertaining to its lawsuit to overturn the order, a ticket reservation prank waged by some users of the video platform that depressed attendance for a campaign rally he held in Tulsa, Oklahoma that June.
