Problem: Background: Jose Julian Marti Perez (January 28, 1853 - May 19, 1895) was a Cuban National Hero and an important figure in Latin American literature. During his life, he worked as a poet, essayist, journalist, translator, professor, and publisher. He was very politically active, and is considered an important revolutionary philosopher and political theorist. Through his writings and political activity, he became a symbol of Cuba's bid for independence against Spain in the 19th century, and is referred to as the "Apostle of Cuban Independence."
Context: January 12, 1895, the North American authorities stopped the steamship Lagonda and two other suspicious ships, Amadis, and Baracoa at the Fernandina port in Florida, confiscating weapons and ruining Plan de Fernandina (Fernandina Plan). On January 29, Marti drew up the order of the uprising, signing it with general Jose Maria Rodriguez and Enrique Collazo. Juan Gualberto Gomez was assigned to orchestrate war preparations for La Habana Province, and was able to work right under the noses of the relatively unconcerned Spanish authorities. Marti decided to move to Montecristi, Dominican Republic to join Maximo Gomez and to plan out the uprising. The uprising finally took place on February 24, 1895. A month later, Marti and Maximo Gomez declared the Manifesto de Montecristi, an "exposition of the purposes and principles of the Cuban revolution". Marti had persuaded Gomez to lead an expedition into Cuba. Before leaving for Cuba, Marti wrote his "literary will" on April 1, 1895, leaving his personal papers and manuscripts to Gonzalo de Quesada, with instructions for editing. Knowing that the majority of his writing in newspapers in Honduras, Uruguay, and Chile would disappear over time, Marti instructed Quesada to arrange his papers in volumes. The volumes were to be arranged in the following way: volumes one and two, North Americas; volume three, Hispanic Americas; volume four, North American Scenes; volume five, Books about the Americas (this included both North and South America); volume six, Literature, education and painting. Another volume included his poetry. The expedition, composed of Marti, Gomez, Angel Guerra, Francisco Borreo, Cesar Salas and Marcos del Rosario, left Montecristi for Cuba on April 1, 1895. Despite delays and desertion by some members, they got to Cuba. They landed at Playitas, near Cape Maisi and Imias, Cuba, on April 11. Once there, they made contact with the Cuban rebels, who were headed by the Maceo brothers, and started fighting against Spanish troops. The revolt did not go as planned, "mainly because the call to revolution received no immediate, spontaneous support from the masses." By May 13, the expedition reached Dos Rios. On May 19, Gomez faced Ximenez de Sandoval's troops and ordered Marti to stay rearguard, but Marti separated from the bulk of the Cuban forces, and entered the Spanish line.
Question: did he have critics
Answer:

Problem: Background: David Bruce Vitter (born May 3, 1961) is an American lobbyist, lawyer and politician who served as United States Senator for Louisiana from 2005 to 2017. He was the first Republican elected to the Senate from his state since the Reconstruction Era. Previously, he served in the United States House of Representatives, representing the suburban Louisiana's 1st congressional district. He served as a member of the Louisiana House of Representatives before entering the U.S. House.
Context: Vitter has been actively involved with legislation concerning illegal immigrants. In June 2007, he led a group of conservative Senators in blocking federal Immigration Legislation that would have granted a pathway to legal residence to 12 million illegal immigrants coupled with increased border enforcement. The bill's defeat won Vitter national attention as the bill was supported by President George W. Bush, John McCain, and Ted Kennedy, among others. Vitter characterized the bill as amnesty, which supporters denied. Bush accused the bill's opponents of fear mongering. In October 2007, Vitter introduced an amendment withholding Community Oriented Policing Services funds from any sanctuary city which bans city employees and police officers from asking people about their immigration status in violation of the Illegal Immigration Act. Democratic Senator Dick Durbin, in opposition to the amendment, said these cities do not want to inquire about someone's status if they report a crime, are a victim of domestic violence or get vaccinations for their children. The amendment was defeated. In November 2007, Vitter introduced a bill requiring banks to verify that no customer was an illegal immigrant before issuing banking or credit cards. The bill never made it out of committee. In March 2008, Vitter reintroduced the latter two proposals and cosponsored ten of eleven other bills in a Republican package of tough immigration enforcement measures including jail time for illegal border crossing; deportation for any immigrant (legal or illegal) for a single driving while intoxicated; declaration of English as the official language (thereby terminating language assistance at voting booths and federal agencies)' additional construction of a border fence; permission for local and state police to enforce immigration laws and penalties for states who issue drivers licenses to illegals. None of these proposals passed, partially because the Democratic-controlled Senate preferred a comprehensive approach which would include a guest-worker program and a path to citizenship for the current population more akin to the package defeated by Vitter in 2007. In April 2008, Vitter introduced a joint resolution proposing a constitutional amendment that a child born in the United States is not a citizen unless a parent is a citizen, lawful permanent resident, or alien serving in the military. Currently the Constitution grants citizenship to children born within the U.S. regardless of the legal status of the parents. The bill never made it out of the Democratic-led committee.
