President Trump reportedly mulled donating money to defeat Sen. Jeff FlakeJeffrey (Jeff) Lane FlakeSenate confirms four Biden ambassadors after delay Flake donating unused campaign funds to Arizona nonprofit focused on elections: report Biden nominates former Sen. Tom Udall as New Zealand ambassador MORE (R-Ariz.).
Two sources familiar with the conversation last fall told Politico that Trump considered the idea of spending $10 million out of his own pocket to defeat Flake.
Flake was a vocal critic of Trump during the 2016 presidential campaign.
In June of last year, he said he couldn't see himself voting for Trump.
After the "Access Hollywood" video surfaced during the presidential campaign of Trump making lewd comments about women, Flake tweeted: "America deserves far better than @realDonaldTrump."
Since Trump was elected, Flake has also spoken out against some of the president's actions.
After Trump issued his initial travel ban, Flake called the order "unacceptable" amid concerns that it would prevent legal permanent residents from entering the U.S.
"Enhancing long term national security requires that we have a clear-eyed view of radical Islamic terrorism without ascribing radical Islamic terrorist views to all Muslims," Flake said in a statement in January.
Flake also called for Trump to apologize for his claim earlier this year that former President Obama had wiretapped Trump Tower before the November elections.
