Fletcher won the right to a second term over GOP challenger Wesley Hunt.
Wednesday morning, Hunt shared that he was humbled by the support he received and that he called Fletcher to congratulate her.
"This campaign was powered by the countless hours of hard work from our fantastic volunteers," Hunt began in a Twitter thread. "I called Congresswoman Fletcher this morning to congratulate her and wish her luck in the next term representing the 7th Congressional District."
"Winning the Republican nomination in this district was among the greatest honors in my life," he continued.
This has been a remarkable year and I am humbled by the support our campaign received from people here in Houston and across Texas. This campaign was powered by the countless hours of hard work from our fantastic volunteers.— Wesley Hunt (@WesleyHuntTX) November 4, 2020
They say politics is a team sport and it is an honor to have the support and dedication of so many incredible Texans. I would also like to thank my wife Emily and my family for their unwavering support throughout this process.— Wesley Hunt (@WesleyHuntTX) November 4, 2020
The TX-7 seat was held by Republicans for five decades before Fletcher's upset win in 2018 over Congressman John Culberson, who had served for nine terms.
Because of the 2018 shakeup, the TX-7 campaign has seen a huge amount of advertising dollars.
The district starts on Houston's west side, covering West University Place, Bellaire and River Oaks. It also includes a thin stretch bounded by I-10 and Westheimer Road, Cypress and Jersey Village.
Fletcher is a native Houstonian known for her moderate voting record.
Hunt is a West Point grad and Army veteran, and like Fletcher, is a native Houstonian.
Hunt was notably endorsed by President Donald Trump during the primary election.
