Elon Musk quietly donates 'very substantial' amount to PAC to canvass Hispanic voters

Fox News has also learned that the latest FEC filings for The Hispanic Voters Alliance will be released to the public on Thursday and will reveal the extent of Musk's financial support. Musk's donation to the PAC came from Musk directly and not through one of his PACs or organizations. The PAC has used the money in recent weeks to get out the Hispanic vote for Republicans. 

The PAC is associated with Rep. Tony Gonzales, R-Texas. Gonzales hosted Musk during the billionaire's visit to the Texas border in Eagle Pass, Texas, last year.
