UPDATE: NBC News projects that U.S. Rep. Marsha Blackburn will become Tennessee's newest junior U.S. Senator, taking the seat held by former Chattanooga mayor and current U.S. Sen. Bob Corker.

Senator-Elect Blackburn said she will not let Tennesseeans down.

"You have sent a message that it is time to take Tennessee conservative values to Washington and keep our state and our country moving forward. I am so incredibly grateful to each of you for doing your part, standing with me, staying strong and turning out the vote. It is such an honor to be the first woman elected to the U.S. Senate from Tennessee. I am going to work as hard for you as you have worked for me. Just as we said on day one, I will take our shared Tennessee values to work on issues of importance to you in Washington: more constitutional federal judges and Supreme Court Justices, lower taxes, less regulation, protecting the right to life, defending the Second Amendment, providing for our troops and veterans, getting the federal budget under control and building the wall once and for all on the southern border. Thank you for believing in me and giving me this opportunity. This is very humbling, and I will not let you down.”

Senator Bob Corker tweeted Tuesday night that he called and congratulated Congressman Blackburn on her win.

A spokesperson for the Republican National Committee also congratulated Rep. Blackburn.

“Unfortunately for Phil Bredesen, he’s not going to be able to just shake it off. Congratulations, Senator-elect Blackburn!" Garren Shipley, RNC spokesman, said.

"Marsha Blackburn ran an outstanding campaign from start to finish. When the pundits had all but counted her out, she just fought harder. Marsha is the conservative champion we need in Washington to fight for the Trump agenda.

Tennessee Lt. Governor Randy McNally said Rep. Blackburn will "make America great again.

She fought for Tennessee values in the legislature and in Congress. She will now continue the fight as Senator. I am grateful she will join a Senate majority in Washington committed to putting America First. Having served at the state level as well as the federal level, Marsha will help bring power back to the states and truly make America great again."

Blackburn was elected to Tennessee’s 7th Congressional District in 2002.

Blackburn is running to replace Republican Senator Bob Corker who decided not to seek re-election. It's expected to be a close race between Blackburn and Democratic Senate hopeful Phil Bredesen who previously was governor for the state.

President Donald Trump and Vice President Mike Pence have made a strong push for Blackburn in the midterm elections. They held a rally for her on Sunday in Chattanooga at McKenzie Arena.

Blackburn will be holding her election night event in Franklin. Channel 3 will have a crew there as results come in from across the state.
