Back from California where he helped make the pitch for Boston to host the 2024 summer Olympics, Boston Mayor Martin Walsh on Wednesday said proponents put on a "strong performance" but added that bringing the games to the Bay State is not his top priority.

Boston, Los Angeles, San Francisco and Washington D.C. are competing to become the first U.S. city to host the Olympics since Atlanta in 1996. After listening to presentations on Tuesday, the U.S. Olympic Committee (USOC) voted to pursue a submission of a U.S. city hosting the Olympics.

Walsh and the others weren't able to see other cities' presentations. At Boston 2024's presentation, Walsh was joined by Suffolk Construction CEO John Fish, one of the top backers of the bid, UMass Boston Chancellor Keith Motley, architect David Manfredi and Cheri Blauwet, a three-time Paralympian.

"I heard they all did pretty well," Walsh said of the other U.S. cities. "But I think Boston did a great job. You know, one thing as I said yesterday, even if we don't get chosen, Boston's in a very strong position as far as moving forward as a city."

Walsh said he has read Boston 2024's bid, which has not been made public. No Boston Olympics, a group opposed to bringing the games to Massachusetts, is pushing for the bid's release.

Asked whether the bid can now be released publicly, Walsh said that's a question for the USOC. "They have some real stringent rules -- that's one of the problems we have here -- around what their procedures are," Walsh said. "And that's one of the frustrating things for me, as far as being able to get out and talk more about it openly."

Walsh, who spoke to reporters while in the North End to highlight a new solar panel at the North Bennet Street School, said the discussion of venues remains "very fluid" and there will eventually be a public discussion on the topic.

"Nothing is in writing, there's no guarantee where any of these venues will be, so there's going to be plenty of conversation around, with the public, about where these different venues are," Walsh said.

"We are not going to be putting money into building venues," he added. "There's going to be a lot of collaboration with the universities and colleges, and possibly city-owned land that we could build on, but we will not be investing financially in a venue."

Walsh said he does not want to leave behind debt from the Olympics if the city is chosen.

A projection of the tab to taxpayers has not been done yet, he acknowledged, while suggesting that previously approved state capital spending on infrastructure could be aligned to meet Olympics needs.

"A lot of the money that we're looking at is transportation money, and that's already in a transportation bond bill the legislature approved last year," he said.

"The public safety aspect of it would be a large cost, the federal government takes that cost up, it's about $2 billion the federal government puts into that, the security piece of it...100 percent of the cost," Walsh added.

Walsh said he does not view the Olympics as high priority but a "piece of a potential down the road."

"It's not my top priority. My top priority is running the city of Boston," he said. "My top priority is making sure that we have homeless shelters, making sure we have places for our rehab programs, making sure we have balanced budgets and our educational system gets better."

He recently spent 48 hours in Colorado Springs and on Tuesday spent less than 20 hours in Redwood City, California, Walsh said. The flight to Colorado Springs was paid out of his campaign account, he said, while Tuesday's trip was paid for by the USOC.

No Boston Olympics, which claims it has thousands of supporters and hundreds of volunteers, released a statement after Tuesday's proceedings.

"This bid would have an outsized impact on Greater Boston and dominate our civic conversation for the next ten years," the group said. "The presentation occurred behind closed doors at a Bay Area office park, where the 15 USOC Board Members and USOC staff reviewed Boston2024's detailed bid. Unfortunately, the citizens and taxpayers of Massachusetts still do not have access to that bid, and were not invited to hear or respond to what promises Boston2024 made to the USOC."

Boston 2024, the group pushing the Olympics bid, also issued a statement Tuesday.

"Boston 2024 was honored to meet once again with the USOC and make our case as to why Boston would be an ideal host for the Summer Games in 2024," Boston 2024's Erin Murphy Rafferty said. "Four great cities were before the USOC today and we feel Boston made a very strong presentation to the committee that focuses on the many strengths of our city and region. This is the next step in what we hope will be a long and productive partnership with the USOC, as well as a thoughtful discussion about where we want to take our city in the coming decades. If Boston moves on to the next phase, we look forward to exploring the possibilities of a Boston Olympics that would be innovative, sustainable and transformative to Massachusetts."

Governor-elect Charlie Baker on Tuesday expressed enthusiasm about the possibility of the Olympics coming to Massachusetts.

"The big issue for me on the Olympic bid is if the [U.S. Olympic Committee] says yes, what they really do is they bless Massachusetts and Boston to make our case to the rest of the world," Baker told reporters. "And it's this pretty unique opportunity to promote Massachusetts and Boston to the participating countries, I think there are 150 all in around the globe. But I think that's a great opportunity to sell the region that gets way beyond just the Olympics."

Former candidate for governor Evan Falchuk, who is seeking to build the United Independent Party, fears a Boston Olympics would consume tax dollars that he says are better spent on other initiatives.

"If you were asked, 'What do you think our state needs most?' it's pretty doubtful you would answer, 'to host the Olympics,' " Falchuk said in a statement. "No, we don't need new, taxpayer-backed stadiums. What we do need is more housing; better school funding; less expensive healthcare; more job opportunities and job training; greater commitment to veterans' services and seniors' programs; and a much stronger business climate. And we need these things all across the state - not just in the Greater Boston area."
