How it unfolded
On March 23, 2026, in Washington, D.C., Senator Martin Heinrich made headlines with his announcement to vote in favor of Markwayne Mullin’s confirmation as Secretary of Homeland Security. This decision comes as a surprise to some, given Heinrich’s previous criticisms of other officials in the Trump administration, including Kristi Noem during her tenure in the same role.
Heinrich’s support for Mullin is rooted in their established working relationship, which has included co-authoring legislation. “This is going to surprise some people, but I consider Markwayne Mullin a friend,” Heinrich stated, highlighting the personal rapport that has developed between the two senators.
In a political landscape often marked by division, Heinrich’s willingness to back Mullin signals a pragmatic approach to governance. He previously supported Doug Burgum’s nomination to lead the Interior Department in January 2025, further illustrating his collaborative stance with Republican colleagues.
However, Heinrich’s political actions are not without controversy. He has been vocal in his opposition to the SAVE Act, a piece of legislation that he argues would disenfranchise vulnerable populations, including rural voters, veterans, and women who have taken their husband’s last names. Heinrich criticized the act, stating, “The SAVE Act does not save anyone from anything. It does not protect our freedoms.”
The SAVE Act proposes requiring proof of citizenship to register to vote, a measure Heinrich believes would create unnecessary barriers to voting. He has actively engaged in discussions regarding the threats to voting rights, hosting a roundtable to address these concerns in light of the Trump administration’s policies.
As the confirmation vote approaches, Heinrich’s support contrasts sharply with that of his colleague Ben Ray Luján, who has announced he will vote against Mullin’s confirmation. This division among Democrats underscores the complexities of party dynamics in the current political climate.
Currently, the Senate is preparing for the confirmation vote, which will determine Mullin’s fate as Secretary of Homeland Security. Heinrich’s backing could play a pivotal role in securing the necessary votes for Mullin, especially given the tight margins in the Senate.
Ultimately, Heinrich’s actions reflect a broader narrative about political alliances and the ongoing debates surrounding voting rights in America. His support for Mullin, coupled with his criticism of the SAVE Act, positions him as a key player in discussions that will shape the future of voting access in the country.
