In 2015, Munisteri announced he would be joining Senator Rand Paul's team of senior advisors.
According to the Republican Party of Texas his resignation is effective March 7, 2015.
 In an official statement explaining his reasoning behind the decision Munisteri writes: 
Today I informed the SREC that I will be stepping down on March 7th.
I have done so, in part, in order to accept the position of Senior Advisor to Senator Rand Paul of Kentucky.
Senator Paul shares my vision of promoting the conservative values of individual freedom, limited government, a strong national defense, and defense of the Constitution in each and every community in our country.

 
Munisteri said he's supporting Paul, in part because of the Kentucky Republican's strategy to court nontraditional GOP voters, like African-Americans and young people.

He also noted that in 2008 the party had only held 45% of the offices across the state.
