In a surprising announcement, Republican Congressman Ken Buck of Colorado's 4th Congressional District revealed on Tuesday that he will be resigning from his position before the end of his term. This decision comes after Buck had previously confirmed he would not seek reelection in November. The congressman's resignation is set to take effect on March 22, creating a vacancy that will further diminish the GOP's majority in the House.

Expressing gratitude to the constituents he has served for the past nine years, Buck released a statement acknowledging the honor of representing Colorado's 4th District in Congress. He expressed his appreciation for the support and encouragement he received from the people. Looking ahead, Buck mentioned his intention to remain engaged in the political process while also dedicating more time to his family in Colorado.

During discussions with reporters at the Capitol later in the day, Buck cited the dysfunction and increasing polarization in Congress as contributing factors to his decision. He specifically highlighted the impeachment proceedings against Homeland Security Secretary Alejandro Mayorkas and the ongoing impeachment probe against President Biden. Buck voiced his opposition to both actions, emphasizing that he believes they are not appropriate.

Earlier, Buck appeared on CNN and described his recent experience in Congress as troubled, stating that it has been the most challenging year of his nine-year tenure. This sentiment has raised questions and curiosity among House leaders on Capitol Hill, including Rep. Steve Scalise, the House majority leader, who expressed interest in understanding the reasons behind Buck's early departure.

Meanwhile, House Speaker Mike Johnson sought to find common ground and unity within the Republican party despite the narrower majority. Johnson remained confident in their ability to maintain a coalition by building consensus, stating that they will not compromise their core principles but are determined to get the job done.

According to constitutional obligations, a special election will be needed to fill the vacancy in the House. In Colorado, the governor is responsible for setting the date for the special election, which must take place more than 90 days before the general election.

With Buck's imminent departure, Rep. Lauren Boebert, a Republican representing Colorado's 3rd Congressional District, has announced her candidacy for his seat. The Republican primary election is scheduled for late July. Notably, the 4th Congressional District encompasses a vast area, including the rural eastern half of Colorado, Douglas County in the southern part of the Denver metro area, and the city of Loveland in Northern Colorado. Since 1973, the district has predominantly had Republican representatives, with Democrat Betsy Markey serving a term from 2009 to 2011.

As Buck prepares to step down from his position, the effects of his resignation will be closely watched as the GOP's majority in the lower chamber narrows from three seats to two. The impact on party dynamics and future legislative efforts remains to be seen.
