Sinema is looking at significantly beefing up the reconciliation bill’s funding for droughts and water security in the Southwest, sources familiar with her thought process tell Axios.

She views the current $369 billion climate and energy portion of the bill as insufficient for addressing threat resiliency funding.

On taxes, Sinema has concerns with the structure of the 15% corporate minimum “book tax” and whether the burden could get passed down to employees, the sources said.

Sinema supports cracking down on tax avoidance, but has long voiced her opposition to closing the carried interest loophole.

She’s concerned that the provision, which would contribute $14 billion toward paying down the bill’s $740 billion total, could undermine economic competitiveness, the sources said.
