His unusual governing arrangement with President Trump is opening Republicans up to being yoked politically to Mr. Musk, who polls show is broadly unpopular.

In an attempt to motivate their voters and donors, a leading Democratic outside group recently launched ads in nearly two dozen House races to seize on Elon Musk’s role in slashing jobs in the federal government and paint GOP incumbents as willing to cut spending on health care for children and elderly to benefit billionaires.

Billionaire Elon Musk is telling Republican lawmakers that he is not to blame for the firings of thousands of federal workers, including veterans, as pushes to downsize the government. Instead, he said in private talks this week that those decisions are left to the various federal agencies.

Trump said he wants his Cabinet to “keep good people” as he addressed sweeping government cuts – but he also warned that “we’re going to be watching.”

The billionaire gave senators his cellphone number to report any mistakes. If I had to guess, Musk is going to be fielding a lot of calls.

The exchange reportedly occurred when Trump called his cabinet into the Oval Office to clarify the scope of Musk's authority.
