The midyear campaign finance reports are in at Dallas City Hall, and they offered a grab bag of insights about the flow of money on the local political scene.

What they didn't yield was many clues about the most interesting question in local politics — who will run for mayor in 2019.

Apart from sitting council members who must submit finance reports, none of the prospective mayoral candidates tipped their hands by filing.

Here are four things that were notable in the reports:

Donating scandal-tainted money

Council member Philip Kingston's report raised questions about a charitable donation he promised to make. Kingston was one of five sitting council members who received campaign contributions from people at the center of an FBI bribery investigation into Dallas County Schools. Kingston, Adam Medrano, Scott Griggs and Mark Clayton all said they would donate money to charity, and Adam McGough pointed out his campaign had been donating to charity for years.

But Kingston's finance report showed no such distribution to charity. Asked about that, Kingston told The Dallas Morning News that he instead used personal funds, rather than campaign funds, to give to the Woodrow Wilson High School Community Foundation. He said he chose to donate his personal money because he wanted to do so.

"It just seemed like a better thing to do," he said. "I've been meaning to contribute to Woodrow for a while."

When asked if he would deduct the donation on his taxes, he said, "I don't discuss that with anybody."

Kingston said he wasn't sure if he still had a record of the donation, but that he gave $3,000 in February or early March. The foundation told The News that Kingston, who represents areas of central and eastern Dallas, did recently make a donation, but didn't have the exact details available this week.

Council member Mark Clayton, who also received campaign funds tied to Dallas County Schools, listed a $5,000 donation to the Aberg Center for Literacy in his district. Council member Scott Griggs donated the $3,000 he received to a city crossing guard program that was jeopardized as a result of financial collapse at Dallas County Schools, a governmental agency that managed school buses and crossing guards for a host of area school districts.

When Griggs, who represents North Oak Cliff, announced in February that he would be giving away the funds, he also said Deputy Mayor Pro Tem Adam Medrano planned to do the same. Medrano’s report showed some "event expenses" that he also listed as donations. He said he had donated $4,300. Not all of those expenditures were listed on the latest report, Medrano said via Twitter. A $300 donation will be listed on a future report, he said. He said Thursday he'd speak to his treasurer about the issue of the way the donations were listed.

Dining out

Council member Tennell Atkins, who spent $15,000 of the $23,000 he received in donations, used around $2,300 for food and beverage expenses, with meals out at a range of spots, from Nick and Sam’s Steakhouse to KFC. Atkins represents far southern Dallas.

Keeping her cards close

Council member Jennifer Staubach Gates is one of the council’s most powerful fundraisers and someone widely seen as a potentially strong mayoral candidate. She took in just $100 in contributions, but still has a large nest egg of $61,500 in the bank. Gates, who represents a swath of northern Dallas, has said she hasn’t decided whether she will run for mayor. She plans a decision later this year.

An incomplete report

Mayor Pro Tem Dwaine Caraway, who has had issues with filing finance reports in the past, initially reported $5,500 in political contributions, but did not report any expenses or the amount of cash he has on hand. More than two hours after The News reached out to him for comment Wednesday, Caraway filed a corrected report that listed $9,250 in contributions and $6,683 in expenses. He again didn't list any cash on hand.
