UNION CITY, N.J. (AP) - To his critics, U.S. Sen. Robert Menendez is the bad guy who always wiggles away. To defenders, he's a respected figure persecuted in whispers and investigations.
The New Jersey Democrat finds himself in familiar territory as his office acknowledges he flew on a donor's plane to the Dominican Republic in 2010 _ but says he did not engage in sex with prostitutes there, as a conservative website reported.
In his gritty, immigrant-heavy northern New Jersey hometown sometimes called "Havana on the Hudson," Menendez is revered as the Cuban-American who has risen the highest in politics and gets high marks for his work for the community.
Antonio Paz, who came to Union City from Cuba 58 years ago, said that he is a Republican with political views different from Menendez's, but that he respects the senator as a leader and is untroubled by the accusation about prostitutes.
"What's the matter?" he said. "In Europe, they give medals for that."
Others find the allegations incredible.
"Could this U.S. senator be so stupid or arrogant to engage in this type of action when he knows that everything he does will be scrutinized during his career?" said Brigid Harrison, a Montclair State University political scientist.
Menendez did not respond to a request by The Associated Press to comment for this article.
While Menendez, 59, has never been charged with a crime, there is no denying that he's often caught in ethical crosshairs.
The son of parents who came to New York from Cuba just before he was born, Menendez was a 19-year-old college student when he petitioned in 1973 to make the school board in Union City elected instead of appointed. At age 20, he was among the first elected to it.
He was a protégé of Mayor William Musto. But in 1982, when Menendez was the secretary for the city's Board of Education, he testified against Musto in a racketeering trial. Menendez was threatened and took to wearing a bulletproof vest, but his testimony helped convict the longtime powerbroker.
Still, Musto had the last laugh, winning re-election on the day after he was sentenced _ against Menendez. A court later forced Musto from office.
Menendez was later elected mayor and to the state Legislature, and he won his first congressional election in 1992. Jon Corzine, who left the Senate in 2006 to become governor, selected Menendez to replace him in the Senate.
Menendez spent that year seeking a full term, and a federal investigation of him was a big part of the campaign.
The U.S. attorney's office in New Jersey, led at the time by Chris Christie, a Republican who is now a high-profile governor, was looking into a relationship between Menendez and the North Hudson Community Action Corp., an anti-poverty group.
The agency rented office space from Menendez at the same time he was helping it get federal funding as a member of Congress.
The case was closed in 2011 with no action by the U.S. attorney's office in eastern Pennsylvania, which had taken it over to avoid a potential conflict of interest raised by Menendez's nomination of Christie's eventual successor to the post.
At the time, Menendez said he was vindicated. And Christie, who made his name by going after political corruption, said he stood behind the timing of the investigation but declined to elaborate.
Other allegations surfaced during the 2006 campaign, involving a taped 1999 conversation in which a Menendez adviser allegedly used the senator's name to pressure someone to hire a doctor for local government work.
According to court documents, the doctor Menendez sought believed some of the money from the government contract would be kicked back to the senator. Menendez denied the allegations.
Investigators also looked into whether Menendez improperly steered lobbying business to a startup run by his former chief of staff, according to published reports in 2007.
Menendez last year contributed $18,800 in campaign funds to charity after donor Joseph Bigica admitted to making straw donations to candidates, in violation of federal election law. In that case, Menendez said he was the victim, not the perpetrator.
On Jan. 29, Bigica's brother, Benedetto, pleaded guilty to similar charges. Federal Election Commission records show he also donated $11,500 to Menendez's campaigns over the years, $2,600 of which was already returned.
In January, the senator's role in Washington grew as he became chairman of the Foreign Relations Committee and was a major player in a bipartisan Senate plan to overhaul the nation's immigration laws. He had just been re-elected in a race he won handily.
