Allstate (ALL) is among six major insurers facing a Senate probe into claim payment practices, the Wall Street Journal reported Monday, citing senators' letters.

Sen. Elizabeth Warren (D-Mass.) and Sen. Josh Hawley (R-Mo.) asked insurers to disclose claims closed without payment, including formal denials, the report said.

The senators, according to the report, also sought details on claim-related compensation for employees, contractors and adjusters.

Allstate did not immediately respond to MT Newswires' request for comment.
