Gov. Rick Scott returns to Puerto Rico Tuesday for the second time in three weeks and the seventh time since Hurricane Maria devastated parts of the island. A more detailed schedule will be released later, but Scott is a guest speaker at a summit regarding hurricane recovery.

The published agenda for the Puerto Rico P3 Summit includes "a panel to provide insights from governors regarding recovery after natural disasters and the importance of infrastructure investments and the role of P3s."

Scott's handling of the post-Irma debris removal effort in South Florida was the focus of a three-part report on CBS4 in Miami in recent days that the TV station said drove up the recovery costs by $28 to $30 million. The governor's office has disputed the station's reporting and said he sent in additional resources because existing debris contractors were "overleveraged."

Scott's previous trips to Puerto Rico were in September and November of last year and January, February, March and May.

Scott has maintained that his repeated visits to Puerto Rico, and the recent donation of 25 surplus Florida Highway Patrol cruisers, are not about election-year politics.

Democrats criticized Scott's Puerto Rico visits as "a series of self-serving, self-promotional photo ops" and claimed Scott offended Puerto Ricans recently when he said he did not know what he would have done any differently than President Donald Trump.

The Times has reported that initial estimates that 300,000 Puerto Ricans would resettle in Florida after the hurricane appear wildly inflated.

Puerto Ricans lean Democratic and any shift in the makeup of the electorate is noteworthy because of the state's history of close elections. T last four major statewide elections — two for president and two for governor — were decided by about 1 percentage point each.
