Jacklyn Sheryl Rosen (née Spektor; born August 2, 1957) is an American politician serving as the junior United States senator from Nevada since 2019.

Rosen was born on August 2, 1957, in Chicago, Illinois, to Carol, a homemaker,[2][3][4] and Leonard Spektor, a car dealership owner who had served in the U.S. Army during the Korean War.

[3] Rosen's mother was of Irish, German, and Austrian descent, and her father's family were Jewish immigrants from Russia and Austria.

[8] A former computer programmer with no political experience at the time, Rosen was asked by U.S. Senate Minority Leader Harry Reid, also from Nevada, to run in the 2016 election for the U.S. House seat being vacated by Republican Joe Heck.

[9] During the campaign, Rosen emphasized her support for the Affordable Care Act (Obamacare) and criticized Heller's vote to repeal it in 2017.

She tweeted during the attack, calling the event "reprehensible" and writing, "It's time for us as a nation to come together and denounce hate and violence.

[25][26][27] As of April 2020, FiveThirtyEight found that Rosen's votes aligned with President Trump's legislative positions about 36% of the time.

[32] In April 2019, Rosen was one of 34 senators to sign a letter to Trump encouraging him "to listen to members of your own Administration and reverse a decision that will damage our national security and aggravate conditions inside Central America."

[26] Rosen supports the Affordable Care Act and its provisions that prevent patients from being denied insurance or charged more due to age or a preexisting condition.

She supports allowing citizens to buy into Medicaid as an alternative option to competing with private insurance companies.

"[37] In August 2019, Rosen was one of 19 senators to sign a letter to Treasury Secretary Steve Mnuchin and Health and Human Services Secretary Alex Azar requesting data from the Trump administration in order to help states and Congress understand the potential consequences if the Texas v. United States Affordable Care Act lawsuit prevailed in courts.

They wrote that an overhaul of the health care system would form "an enormous hole in the pocketbooks of the people we serve as well as wreck state budgets".
