“Just signed a critical bill to formalize drought contingency plans for the Colorado River. Thanks to @SenMcSallyAZ for getting it done. Big deal for Arizona!” Trump tweeted Tuesday that McSally retweeted.

The law Trump signed codifies an agreement between Arizona, Colorado, Wyoming, Utah, California, New Mexico and Nevada to establish voluntary water conservation measures as the states try to manage prolonged drought conditions and regional impacts of climate change.

Sinema’s victory made the Grand Canyon State a top priority for Democrats, who have successfully recruited a top-tier challenger in Kelly.

Kelly announced earlier this month he raised a staggering $4 million in the first quarter of 2019, with the average online contribution amounting to $25. The Arizona Democrat also has high name recognition as a former astronaut and husband to former Rep. Gabrielle Giffords (D-Ariz.), who narrowly survived a shooting in 2011. The two have since become high-profile advocates for gun control reform. 

McSally hauled in about $2 million in the first quarter of 2019, according to a Federal Election Commission filing.

Republicans hope to defend their 53-47 Senate majority next year as a handful of GOP incumbents face tough Democratic challengers in states like Colorado, Maine, North Carolina, Iowa and Arizona.
