Batting .500 at the NY Times

From today's NY Times: "Committee leaders claim to be still fact-gathering, but it has becoming clear that their mission is to dismiss this hot potato yet not seem cowardly about it." Kudos on avoiding the split infinitive ("to be still"); better luck next time on avoiding the mixed tense ("has becoming").
