HAVANA (CBSNewYork/AP) -- President Barack Obama landed in Havana Sunday evening to kick off his historic trip to Cuba.
Obama's whirlwind trip is a crowning moment in his and Cuban President Raul Castro's ambitious effort to restore normal relations between their countries. While deep differences persist, the economic and political relationship has changed rapidly in the 15 months since the leaders vowed a new beginning.
Wielding an umbrella on a rainy Havana afternoon, Obama and his family stepped off of Air Force One and were greeted by top Cuban officials -- but not Raul Castro. The Cuban leader frequently greets major world figures upon their arrival at Jose Marti International Airport, but was absent on the tarmac. Instead, he planned to greet Obama on Monday at the Palace of the Revolution.
"This is a historic visit," Obama said as he greeted U.S. Embassy staff and their families at a Havana hotel. "It's an historic opportunity to engage with the Cuban people."
Joined by first lady Michelle Obama and his two daughters, Obama toured Old Havana by foot, walking gingerly on the slippery wet stones in front of the Havana Cathedral. The downpour notwithstanding, a few hundred people gathered in the square erupted in applause and shouted Obama's name as the first family stepped forward.
Approaching the Plaza de Armas, a leafy square in a tenderly restored corner of Old Havana, the Obama were greeted by buoyant chants of "USA, USA."
For more than 50 years, Cuba was an unimaginable destination for a U.S. president, as well as most American citizens. The U.S. severed diplomatic relations with Cuba in 1961 after Fidel Castro's revolution sparked fears of communism spreading to the Western Hemisphere. Domestic politics in both countries contributed to the continued estrangement well after the Cold War ended.
"He wanted to come to Cuba with all his heart," 79-year-old Odilia Collazo said in Spanish as she watched Obama's arrival live on state television. "Let God will that this is good for all Cubans. It seems to me that Obama wants to do something good before he leaves."
Ahead of Obama's arrival, counter-protesters and police broke up an anti-government demonstration by the Ladies in White group, whose members were taken into custody by female police officers in a scene that plays out in Havana each Sunday. They're typically detained briefly and then released.
Sen. Bob Menendez, D-N.J., had harsh words for Obama about his trip to Cuba.
"It is totally unacceptable for the president of the United States to reward a dictatorial regime," Menendez told reporters, including WCBS 880's Kelly Waldron.
Theresa Muniz, a Cuban-American living in Union City, New Jersey, told CBS2's Valerie Castro that it's not the right time for Obama to visit Cub.
"I do feel that there's too much going on in Cuba. Too much poverty, misery and things that have to be resolved before we can actually have a relationship with Cuba," she told CBS2.
Obama's visit was highly anticipated in Cuba, where workers furiously cleaned up the streets in Old Havana and gave buildings a fresh coat of paint. American flags were raised alongside the Cuban colors in parts of the capital, an improbable image for those who have lived through a half-century of bitterness between the two countries.
CBS2's Chris Martinez reported from Havana that many Cubans are hopeful Obama's visit will pave the way for more openess between the island nation and the U.S.
"I think we're gonna have some changes, but it's going to be slow," Lulu Pinieira of Havana told CBS2.
Many Cubans were staying home in order to avoid extensive closures of main boulevards. The city's seaside Malecon promenade was largely deserted Sunday morning except for a few cars, joggers, fishermen and pelicans.
The president's schedule in Cuba is jam-packed, including an event with U.S. and Cuban entrepreneurs. But much of Obama's visit was about appealing directly to the Cuban people and celebrating the island's vibrant culture.
"I don't think that the Cuban people are going to be bewitched by North American culture," Gustavo Machin, Cuba's deputy director of U.S. affairs, told The Associated Press. "We don't fear ties with the United States."
A highlight of Obama's visit comes Tuesday when he joins Castro and a crowd of baseball-crazed Cubans for a game between the beloved national team and Major League Baseball's Tampa Bay Rays. The president also planned a speech at the Grand Theater of Havana laying out his vision for greater freedoms and more economic opportunity in Cuba.
Two years after taking power in 2008, Castro launched economic and social reforms that appear slow-moving to many Cubans and foreigners, but are lasting and widespread within Cuban society. The changes have allowed hundreds of thousands of people to work in the private sector and have relaxed limits on cellphones, Internet and Cubans' comfort with discussing their country's problems in public, for example.
The Cuban government has been unyielding, however, on making changes to its single-party political system and to the strict limits on media, public speech, assembly and dissent.
Obama will spend some time talking with Cuban dissidents. The White House said such a meeting was a prerequisite for the visit. But there were no expectations that he would leave Cuba with significant pledges from the government to address Washington's human rights concerns.
"I think the people want to hear honesty from Obama, that he actually respects the Cuban society and what we believe in," Cuban journalist Cristina Escobar told CBS2.
A major focus for Obama was pushing his Cuba policy to the point it will be all but impossible for the next president to reverse it. That includes highlighting new business deals by American companies, including hotel chains Starwood and Marriott and online lodging service Airbnb.
The president's visit to Cuba wraps up on Tuesday.
