Alabama Republican Rep. Mo Brooks has taken a step closer to officially running for an open Senate seat in his home state – hyping a "exciting announcement" Monday with former President Trump adviser Stephen Miller.

"Please join Congressman Mo Brooks and special guest Stephen Miller for an exciting announcement," Brooks tweeted Wednesday.

Miller was a top Trump immigration policy adviser. 

Brooks ran unsuccessfully in 2017 for the Alabama Senate left open by then-GOP Sen. Jeff Sessions after he was appointed attorney general by Trump.

Miller was also a member of Sessions' Senate staff.

Current Alabama GOP Sen. Richard Shelby is retiring at the end of his term and will not seek 2022 reelection.
