Friend, with Democrats' razor-thin 50-50 majority, Senate control will come down to battleground races – like mine in Georgia and my friend Sen. Mark Kelly's in Arizona. That's why this news is so concerning:

After holding major rallies in Georgia, Donald Trump is holding another rally in Arizona ahead of the primary election – all so he can fire up the GOP base, prop up his extremist candidates, and flip Mark's Senate seat red. 

With CNN calling Mark and me two of the most vulnerable Democratic senators up for reelection, we don't have a second to spare: Before midnight tonight, will you split a donation of $5 or more between Mark Kelly’s campaign and mine so we can defend our battleground seats and keep the Senate blue?

Mark is exactly the kind of leader we need in the Senate, and I'm proud to work alongside him. As a former Navy captain, engineer, and astronaut, Mark knows what it means to look trouble in the face and rise to meet the occasion – and he's brought this same tenacity to the Senate to deliver for working people. 

But with Donald Trump and Mitch McConnell coming after Mark and me with everything they've got, we need to fight back right now – or else we could risk putting our entire majority, along with our bold agenda, in serious jeopardy.

Experts at Nate Silver's FiveThirtyEight say that the Senate is toss-up. The ONLY way we can defend our majority is if grassroots folks help power our reelection campaigns to victory at critical moments like this. 

We're counting on you, friend: Please, will you split a donation of $5 or more now to help Mark and me win our competitive races and defend our razor-thin Democratic Senate majority?

Thank you, friend. We appreciate you. 

– Sen. Raphael Warnock
