Today’s installment of campaign-related news items from across the country.

* In a bit of a surprise, Allegheny County Controller Corey O’Connor defeated Pittsburgh Mayor Ed Gainey in Pittsburgh’s highly competitive Democratic mayoral primary. With just about all of the votes counted, O’Connor appears to have won by roughly 6 points.

* Rep. Gerry Connolly of Virginia, the top Democrat on the House Oversight Committee, died overnight after a fight with cancer. While Connolly had already announced plans to retire, there will now be a special election to fill his seat.

* With Republican Rep. Thomas Massie insisting that he’ll oppose his party’s reconciliation legislation, Donald Trump told reporters that he believes the Kentucky congressman “should be voted out of office.”

* On a related note, Massie soon after launched the kind of fundraising appeal rarely seen in contemporary GOP politics: He asked supporters to send financial support because his party’s president was attacking him.

* Despite the fact that there’s a GOP majority in the House, the Democratic Congressional Campaign Committee outraised its Republican counterpart again in April, $8.1 million to $7 million. Among the parties’ Senate campaign arms, fundraising totals from last month were effectively tied.

* As former Democratic Gov. Andrew Cuomo’s mayoral campaign in New York City continues, the Trump Justice Department announced that it has launched an investigation into congressional testimony Cuomo offered last year.

* Former Republican Rep. Matt Gaetz’s on-again, off-again interest in Florida’s gubernatorial race is apparently back on again, according to an NBC News report.

* And Donald Trump Jr. appeared at the Qatar Economic Forum in Doha and suggested he might follow in his father’s footsteps and launch a presidential campaign of his own someday. “You never know,” he said at the event. “The answer is, I don’t know, maybe one day. You know, that calling is there.”
