On July 18, 2018, hours after Sinclair submitted a revision to the acquisition proposal that rescinded plans for WGN-TV and CW-affiliated sisters KDAF in Dallas–Fort Worth and KIAH in Houston to be sold to closely tied third-party companies—WGN-TV LLC and Cunningham Broadcasting, respectively—in order to address concerns expressed by FCC chairman Ajit Pai concerning the partner licensees Sinclair proposed using to allow it to operate certain Tribune stations in circumvention of the 39% national ownership cap, the FCC Commissioners' Board voted unanimously, 4–0, to send the Sinclair-Tribune acquisition proposal to an evidentiary review hearing before an administrative law judge amid "serious concerns" about Sinclair's forthrightness in its applications to sell certain stations in markets where Sinclair and Tribune both had television properties. On August 9, 2018, Tribune announced it would terminate the Sinclair deal, and concurrently filed a breach of contract lawsuit in the Delaware Chancery Court, alleging that Sinclair engaged in protracted negotiations with the FCC and the DOJ over regulatory issues, refused to sell stations in markets where it already had properties, and proposed divestitures to parties with ties to Sinclair executive chair David D. Smith that were rejected or highly subject to rejection to maintain control over stations it was required to sell.
