Two pro-Trump allies have launched Senate campaigns as five Republican Senators have announced they will not run for re-election. Congressman Mo Brooks is running to succeed the seat left by Sen. Richard Shelby who announced his retirement. Also, former Missouri governor Gov. Eric Greitens announced his Senate campaign to fill the seat left by Roy Blunt who will also retire at the end of his term saying he is a “fierce defender of President Trump from Day One.”

Prior to Brook’s official Senate campaign launch, he joined Stephen Miller, a top Trump adviser, who offered his endorsement to the Alabama Congressman and touched on his loyalty to the former president.

Fox News reports:

And in an exclusive national interview with Fox News, the congressman spotlighted his “very good relationship” with Trump, emphasizing that “I have stood by his side during two impeachment hoaxes, during the Russian collusion hoax, and in the fight for honest and accurate elections. The president knows that. The voters of Alabama know that, and they appreciate it.”

About an hour before Brooks officially launched his campaign to succeed retiring longtime GOP Sen. Richard Shelby, former Missouri Gov. Eric Greitens announced his candidacy for the Senate during an appearance on Fox News’ “Special Report.”

Greitens told Bret Baier that the people of Missouri “need somebody who is going to go – as I will, as I am committed to do – to defending President Trump’s ‘American First’ policies and also to protecting the people of Missouri from Joe Biden, Nancy Pelosi and Chuck Schumer’s radical leftist agenda.”

Rudy Giuliani formally endorsed Greitens’ Senate campaign. On Twitter, Greitens referred to Giuliani as “America’s Mayor” and thanked him for the support.

Now, the two Republicans are waiting to hopefully receive endorsement from Trump, who’s taken on a “kingmaker” role within the party.
