Washington (CNN) House Majority Whip Steve Scalise officially put himself in the running to become House Majority Leader, announcing his decision in a Tuesday morning letter to his House GOP colleagues.

"I understand from experience that unity is easy to call for, but it takes the right kind of leadership to achieve," the Louisiana congressman wrote in the letter. "Whenever you've called on me, I've delivered. Together, we've confronted many challenging issues, and each time I've worked to bring all parts of our conference together to pass legislation that reflects our values and moves our country forward."

"As your Majority Leader, we'll build upon this inclusive approach to deliver results you can be proud of," he added.

Scalise was widely expected to seek the position after it became clear House Majority Leader Kevin McCarthy would vie to succeed Rep. John Boehner as the next House speaker. Boehner announced last week that he was resigning from Congress at the end of October.
