Elon Musk has quietly become the biggest known donor in this year's midterm elections.

Since July, he has given more than $276 million.

He wants to help Republicans keep control of Congress.

The New York Times first reported the numbers.

Andrew Romeo confirmed them.

He is a spokesperson for Musk's super PAC.

The money includes $158 million to the Senate Leadership Fund.

This is the main super PAC for Republican Senate candidates.

The Times called it one of the largest political donations in American history.

Another $76 million went to America PAC.

This is Musk's own super PAC.

It has built a big operation to get people to vote.

Musk also gave $10 million to Lone Star Liberty PAC.

This group supports Ken Paxton.

He is the Republican Senate nominee in Texas.

This is a big change.

Last May, Musk said he wanted to spend less on politics.

He said he had done enough.

He has also kept a lower profile than in 2024.

Back then, he stood on stage with Trump at rallies.

Later, he had a fight with Trump.

But the two have made up since then.

Last week, Trump gave him the National Medal of Science.

Republicans now have a lot more money than Democrats.

This is a rare good sign for a party that may lose seats.

Voters are unhappy about the president's work, high prices and the unpopular war with Iran.

Romeo said the money lets the GOP "get its message out."

He said it gives Republicans a chance to beat history.

Democrats said Republicans are trying to buy the elections.

Lauren French is with the Democrats' Senate Majority PAC.

She said they are spending tens of millions to beat their unpopular candidates, president and economy.
