The party caucus in the state house was re-recognized in 2017, after Caleb Q. Dyer, Joseph Stallcop, and Brandon Phinney changed their political affiliations to Libertarian.

Since 2020, the party has received coverage in the press for controversial, far-right, and antisemitic statements made by its Twitter account.

[16] Calvin Warburton, who had served in the state house since 1978, changed his political affiliation from Republican to Libertarian and became a dues paying member on July 16, 1991.

He stated that the Libertarians were the only one who stood for economic, personal, and social freedom and was critical of the Republicans for planning to create new taxes.

[18] Representative Donald Roulston, who the party had attempted to recruit in 1989, but declined stating that he was "too much of an anarchist for you", changed his political affiliation from Republican to Libertarian in 1992.

[23] The Libertarian Caucus was recognized by the state house due to having more than three members, but lost its recognition after membership decreased to two in 1995.

[24] Representative Jim McLarin resigned on February 9, 1995, leaving Gorman as the only Libertarian in the state house.

The party sued against this law; they lost the suit when Judge Bruce M. Selya ruled against them in Werme v. Merrill in 1996.

[37] Representative Steve Vaillancourt was given the Libertarian nomination after he lost renomination in the Democratic primary and won reelection during the 2000 election.

[49][50][51] In 2016, the five-member executive committee of the party voted to adopt a resolution calling for the secession of New Hampshire from the United States.

[52] On February 9, 2017, Caleb Q. Dyer, a Republican member of the state house, changed his political affiliation to Libertarian.

[58] The party failed to receive 4% of the vote in the 2018 New Hampshire gubernatorial election causing it to lose its status in the state.

The tweets were written by Jeremy Kauffman, a member of the New Hampshire Libertarian Party's state executive committee.

Jarvis claimed support from Bishop-Henchman based on a letter he wrote her on June 7 recognizing her as chair of the Libertarian Party of New Hampshire.

Former vice-presidential candidate Spike Cohen and former Representative Justin Amash criticized Jarvis' attempted takeover.

[66][67] On Martin Luther King Day, the account claimed that black people are "in debt" to the United States because they "receive special federal funding due to race and are first-in-line for every college and every job."

The tweet also referenced a false claim made by Donald Trump that authorities denied white people access to the COVID-19 vaccine because of their race.

"[75][76] On the fourth anniversary of John McCain's death, the party's Twitter account posted a picture of his daughter Meghan crying at his funeral with the caption "Happy Holidays."

"[77][78] Governor Chris Sununu stated on CNN that the tweets "should pretty much be the end of the Libertarian Party in New Hampshire".

LPNH later deleted its tweet as it violated X's rules, while complaining about restricted speech: "Libertarians are truly the most oppressed minority.
