Orrin Grant Hatch (born March 22, 1934) is an American attorney and politician serving as the senior United States Senator for Utah who has been the President pro tempore of the United States Senate since 2015. Having been a senator since 1977, Hatch is the longest-serving Republican Senator in U.S. history. Hatch served as either the chair or ranking minority member of the Senate Judiciary Committee from 1993 to 2005. He previously served as chairman of the Senate Committee on Health, Education, Labor, and Pensions from 1981 to 1987 and currently serves as Chairman of the Senate Finance Committee as well as serving on the board of directors for the United States Holocaust Memorial Museum.

Hatch opposed President Barack Obama's health reform legislation; he voted against the Patient Protection and Affordable Care Act in December 2009, and he voted against the Health Care and Education Reconciliation Act of 2010. Hatch has argued that the insurance mandate found in the legislation is not in the category that can be covered by the interstate commerce clause since it regulates the decision to engage in commercial activity rather than regulating the activity itself. He therefore regards the Act as unconstitutional. NPR called Hatch a "flip-flopper" on this issue since in 1993 Hatch co-sponsored a bill along with 19 other Senate Republicans that included an individual insurance mandate as a means to combat healthcare legislation proposed by Hillary Clinton. In 2018, Hatch said that Obamacare supporters were "the stupidest, dumbass people I've ever met".  Hatch was one of the first Senators to suggest that the individual mandate was unconstitutional and promised to work on dismantling it when he becomes the Finance Committee Chairman. Hatch was part of the group of 13 Senators drafting the Senate version of the AHCA behind closed doors.  Hatch also Introduced the American Liberty Restoration Act (S. 19 112th Congress). This act would repeal the provisions in the Patient Protection and Affordable Care Act that require individuals to keep minimum essential health care coverage. He also co-sponsored the Save Our States Act (S. 281, 112th Congress), which would delay the implementation of the health care reform law until there is a final resolution of the lawsuits against it.  In 2003, Hatch supported the Medicare prescription drug benefit plan known as Medicare Part D. Responding to criticism of the legislation during the 2009 debate on health care reform, Hatch said that in 2003 "it was standard practice not to pay for things" and that although there was concern at the time about increasing the deficit, supporting the bill was justified because it "has done a lot of good".  On March 25, 2014, Hatch cosponsored the Emergency Medical Services for Children Reauthorization Act of 2014 in the Senate. The bill that would amend the Public Health Service Act to reauthorize the Emergency Medical Services for Children Program through FY2019. The bill would authorize appropriations of about $20 million in 2015 and $101 million over the 2015-2019 period. Hatch argued that "children require specialized medical care, and that specialized care comes with unique challenges. The EMSC program helps ensure that some of our country's most vulnerable have access to the care they need, and I've been proud to support it all these years."
