Attorney General Ken Paxton raised $2.9 million over the first 12 weeks of his bid for U.S. Senate, his campaign announced Friday. Paxton revealed the haul ahead of Tuesday’s deadline for federal candidates to disclose their spending and fundraising activities from the start of April through the end of June.

Sen. John Cornyn has established a wide fundraising advantage over his Texas Republican primary opponent state Attorney General Ken Paxton, according to financial figures obtained by Axios. Why it matters: Cornyn is facing a more serious primary threat than any other senator up for election next year — and will need every dollar he can get.

CNN reports, Cornyn brought in $3.9 million to Paxton’s $2.9 million between April and June. Paxton is challenging Cornyn in what’s shaping up to be one of next year's hottest-contested primaries.
