The tea party darling and possible presidential hopeful has now raised more than $5 million since taking office in January 2013. He has about $2 million in cash on-hand.
Those tallies include Cruz's Senate re-election committee, a joint fundraising committee and Cruz's leadership PAC, Jobs, Growth & Freedom Fund.
Cruz announced Wednesday that from Jan. 1 through March, he received 13,668 individual donations, with all but about 650 of them worth less than $100.
In the final three months of 2013, however, Cruz's campaign coffers received about $1.5 million. That included a bump in donations after Cruz's key role in the government shutdown.
