Republican Josh Hawley raised a little more than a third of what Missouri Sen. Claire McCaskill did during the first quarter of this year.
Hawley's campaign reported Thursday that it raised $1.5 million from January through March. The Democratic senator's campaign reported last week that it had raised more than $3.9 million.
McCaskill also ended March with five times as much cash on hand as Hawley. She reported having $11.5 million to Hawley's $2.1 million.
