Beto O’Rourke, a Democratic presidential candidate and former Texas congressman, has had a rough April.

Two of O’Rourke’s top advisers, Becky Bond and her deputy Zack Malitz, both resigned from the campaign less than a month after O’Rourke announced his presidential bid, reports The Washington Examiner. The reasons Bond and Malitz, who were both involved in O’Rourke’s failed but momentous Senate campaign against Sen. Ted Cruz (R-Texas) in 2018, left remain unclear.

But the departures are just the latest examples of bad news that have struck O’Rourke’s campaign this month. Last week, O’Rourke released his tax returns revealing that he twice slightly underpaid his taxes and has given little to charity. They also showed that he profited off stocks in fossil fuel, cigarette, tech and pharmaceutical companies — four industries which, to put it gently, are not currently beloved by Democratic voters.
