WASHINGTON — And so, it seems, Buffalo Mayor Byron W. Brown and Sen. Kirsten E. Gillibrand will live happily ever after.

Five weeks after Brown expressed his disappointment with Gillibrand’s accessibility while courting her possible Democratic primary challenger—and a day after that challenger dropped out of the race — the mayor and the senator had lunch, at her invitation.

Afterward, Brown had nothing but praise for what he heard from the state’s junior senator.

“It was a good meeting, a very substantive meeting,” Brown said. “She said she had been working on all the items on our legislative agenda. . . . She was very up to speed on the items.”

Gillibrand was equally upbeat about the meeting.

“My meeting with Mayor Brown was very productive,” she said. “We have a strong partnership that I believe will help Buffalo create jobs and grow its economy over the long term. The mayor and I share a vision for how to help this great city, and we will continue to work together to secure more federal resources to support local efforts.”

Back in late January, though, things were not so chummy between Brown and Gillibrand.

Miffed that she had canceled a meeting with him and had never paid a visit to his Buffalo office, Brown said at the time: “We need elected representatives who are going to give us their focus and their attention. I think it is important for the people of Buffalo to feel they are not taken for granted.”

Asked if he discussed those concerns with Gillibrand on Tuesday, Brown said: “It wasn’t necessary because there’s been significant outreach since that time. She knew we were coming to D. C. She called and invited me to lunch to go over priorities.”

And politics didn’t appear to be one of them. Brown said that neither he nor Gillibrand mentioned Harold E. Ford Jr., the former Tennessee congressman who had threatened to challenge Gillibrand before withdrawing from the race Monday.

Brown, who prominently hosted Ford on his two exploratory visits to Buffalo, said he received a call from Ford on Monday in which he said he would not be running.

Brown’s lunch with Gillibrand was part of a two-day lobbying trip to the nation’s capital that features meetings with lawmakers from the Buffalo-area congressional delegation and other important figures.
