Last week, Mayor Martin J. Walsh stood on the tarmac of Logan International Airport to greet President Obama as he swept into Massachusetts on a political fund-raising trip.
This week, Walsh is making the trek to Washington, D.C., to shake a different type of money tree: lining up federal dollars for Boston.
On a two-day journey, Walsh said he will meet with top Cabinet officials to press for funding and deepen connections between their agencies and the city.
Walsh is set to huddle with Jeh Johnson, secretary of Homeland Security, and Gina McCarthy, administrator of the Environmental Protection Agency.
In a telephone interview Sunday, Walsh said he would chat with Johnson about security for the upcoming Boston Marathon and with McCarthy about climate change and preparedness while he is in D.C.
But positioning the city for federal dollars doled out by Cabinet agencies, he said, was a key part of the trip.
“We’ve got to advocate for funding, obviously,” Walsh said.
“You have to try and get grants and be in good positions for grants, and a lot of these different departments have grants,” he said.
Walsh also plans to hold discussions with members of state’s congressional delegation — Representative Michael E. Capuano and Senators Elizabeth Warren and Edward J. Markey — to talk about federal issues ranging from gun control to flood insurance.
After he became mayor in January, Walsh scheduled two trips to Washington, but both were postponed due to snowstorms.
Walsh said he is also going to give a speech to an organized labor conference on Monday night.
Kate Norton, a Walsh spokeswoman, said the mayor has a meeting with US Representative Nancy Pelosi of California, the House’s top Democrat, as well.
Walsh said he was departing Boston Sunday night and returning Tuesday night.
Obama, for his part, came to Massachusetts last Wednesday for two fund-raisers for the Democratic National Committee, one in Cambridge and one in Boston.
At the Boston event, the president lauded Walsh, calling him an “outstanding young new mayor.”
