Moore was banned from the House floor in March 2024 for making controversial comments during a day of remembrance for late Speaker David Ralston.

Nineteen months after graduating college, Moore, then 24, qualified to run against incumbent John Deffenbaugh in the House race for District One.

[11] With no declared Democratic opponent, Republican Moore was elected as the presumptive District 1 State Representative on May 22, 2018, after defeating John Deffenbaugh by a margin of 326 votes with a final tally of 2,184 to 1,858.

In March 2022, Mullis announced he would withdraw from the election following medical issues, claiming he wished to spend more time with his family.

[18] On May 21, 2024, Moore won the Republican primary election for state senator with 70% of the vote against newcomer Angela Pence (29.8%).

Millwood said: "During Colton’s term as a state representative, his frustrations at being blocked and talked down to by Jeff Mullis led him to tackle the problem directly and run for that seat.

I admire his tenacity and ability to go right to the source of the problem and launch a public challenge to make a difference".

[31][32] Moore and friend, Michael Gargiulo, a domain-name expert, "brokered a five-figure name transaction to buy the rights to the site".

Moore drove a truck that was covered in signs, urging people from Catoosa, Walker and Dade to vote for Kemp.

[38] In November 2018, Trump and Vice President Pence visited Chattanooga, Tennessee to campaign for Senator Marsha Blackburn.

David Shell, a man who has beaten many women, including having been charged by a grand jury as a repeat offender, told the Atlanta Journal-Constitution: "That’s why I gave him 20,000 bucks… He’s worth every penny of it".

[43] Moore wrote a letter to Speaker Ralston that read, "While legislative continuance is a right all legislators have access to, your use of this right has resulted in an unjust delay of violent criminal cases in our state… District 1 and many citizens across our great state believe you should no longer serve as the leader of Georgia's largest governing body".

[44] Moore went on to write a memorandum to Kemp, listing the reasons why it would be an inappropriate choice to name the new judicial center after Deal.

[46] On August 29, 2023 while appearing on Steve Bannon's "War Room" podcast, Moore claimed that his constituents could be "fighting in the streets" if Fulton County District Attorney Fani Willis is not prevented from prosecuting former president Donald Trump and his 18 alleged co-conspirators for violations of Georgia's RICO statute and other offenses connected with the attempts to reverse the outcome of the 2020 presidential election.

[49] In a letter to Governor Kemp, Moore called for an emergency session to investigate Fulton County District Attorney Fani Willis, who had indicted Donald Trump and 18 other people on felony charges.

Governor Kemp's office later stated that Moore "has not provided evidence that he has the necessary support to call a special session".

However, during his advocacy for his ill-conceived proposal, Senator Moore has knowingly misled people across Georgia and our nation, causing unnecessary tension and hostility, while putting his caucus colleagues and their families at risk of personal harm".

[54] Moore replied, "The Georgia RINOs responded to my call to fight back against the Trump witch hunts by acting like children and throwing me out of the caucus".

[5] On March 14, 2024, Moore was banned from the House floor after criticizing late Speaker David Ralston in the Senate chamber.

[55] The comments were criticized by senators of both parties, including Republican Tim Bearden and Democrat Josh McLaurin.

All elected 56 senators and 180 representatives deserve the opportunity to fulfill their responsibility to attend joint sessions of the General Assembly.
