[7][8] After the acquittal of George Zimmerman in the Trayvon Martin murder trial, Mayor Holley and Roselle's Borough Council submitted a formal plea to President Barack Obama and U.S. Attorney General Eric Holder to investigate alleged violations of civil rights relating to the 2012 fatal shooting.

Roselle was the first Union County municipality to appeal to the Obama administration for further examination of the case after Zimmerman was found not guilty of second-degree murder and manslaughter charges.

[9] Holley was unanimously chosen by Democratic committee members of the 20th district to fill the Assembly seat of Joseph Cryan, who resigned in 2015 to become the Union County Sheriff.

[13] In 2009, Holley was charged with tampering with ballots in a primary election contest, a third-degree crime which carries a maximum sentence of five years in prison.

[14] Holley waived his right to indictment by a grand jury and agreed to be charged by accusation to filling out 30 absentee ballots.

"[26] Holley maintains an active social media presence and has directed accusatory tweets at Bill Gates, saying he "...injected and caused harm to mulitple [sic] minority families in India and Africa.".
