Tempers are starting to boil within the Senate Republican Conference as disagreements arise over how to handle President Trump's No. 1 legislative priority, the Safeguard American Voter Eligibility (SAVE America) Act, which Trump wants to push through the Senate despite staunch Democratic opposition.
