It also provided fodder for him to shift the public focus away from the special counsel investigation that unveiled criminal charges against three former campaign aides this week. But in an interview with The New York Times on Wednesday, Mr. Trump adamantly denied being concerned about the indictments.
âIâm not under investigation, as you know,â he said in a brief telephone call. Pointing to the indictment of his former campaign chief, Paul Manafort, the president said, âAnd even if you look at that, thereâs not even a mention of Trump in there.â Noting that Mr. Manafort was charged with financial crimes stemming from his lobbying business, the president added: âIt has nothing to do with us.â
Mr. Trump, a lifelong New Yorker, wasted little time Wednesday morning assigning fault for the attack along the bicycle path. âThe terrorist came into our country through what is called the âDiversity Visa Lottery Program,â a Chuck Schumer beauty,â he wrote on Twitter. âI want merit based.â
Mr. Schumer responded from the floor of the Senate, noting that after the attacks of Sept. 11, 2001, President George W. Bush brought Mr. Schumer and Hillary Clinton, then the other Democratic senator from New York, to the White House to demonstrate national unity.
âPresident Trump, where is your leadership?â Mr. Schumer asked. âPresident Trump, instead of politicizing and dividing America, which he always seems to do at times of national tragedy, should be bringing us together and focusing on the real solution â antiterrorism funding â which he proposed to cut in his most recent budget.â
At a news conference updating the public about the attack, Gov. Andrew M. Cuomo of New York chided Mr. Trump for his Twitter posts, saying they âwere not helpful,â were not âeven accurateâ and âtended to point fingers and politicize the situation.â
âYou play into the hands of the terrorists to the extent that you disrupt and divide and frighten people in this society,â said Mr. Cuomo, who is a Democrat. âAnd the tone now should be the exact opposite by all officials on all levels. This is about unification, this is about solidarity.â
At his own public appearance later in the day, Mr. Trump took aim again at the diversity lottery visa program. âDiversity lottery â sounds nice,â he added. âItâs not nice. Itâs not good. It hasnât been good. Weâve been against it.â
Responding to questions by reporters, he said he was open to transferring the suspect, Sayfullo Saipov, from civilian courts into the military system set up for foreign terrorists.
âI would certainly consider that,â he said at the beginning of a cabinet meeting. âSend him to Gitmo, I would certainly consider that, yes.â
Likewise, he vowed to toughen prosecution and punishment of terrorists without specifying how. âWe need quick justice and we need strong justice, much quicker and much stronger than we have right now,â Mr. Trump said. âBecause what we have right now is a joke and itâs a laughingstock.â
No one arrested on American soil has ever been sent to GuantÃ¡namo Bay, and no one captured on foreign soil has been sent there since 2008. Transferring the suspect from New York would raise a host of thorny constitutional and legal issues, and Mr. Trump seemed to be speaking off the top of his head since federal prosecutors later moved to process the suspect in civilian courts.
Asked later about his comment on GuantÃ¡namo, Sarah Huckabee Sanders, the White House press secretary, dismissed it as notional, saying that âhe wasnât necessarily advocating for it, but he certainly would support it if he felt like that was the best move.â
By the end of the day, the president came under criticism from conservative allies for not declaring Mr. Saipov an enemy combatant, which would have allowed interrogators more freedom to question him without granting him the rights of a civilian defendant. âThe Trump administration missed an important opportunity to send a strong message to terrorists and make America safer,â said Senator Lindsey Graham, Republican of South Carolina. âThis is a huge mistake. Very sad.â
The diversity visa program cited by Mr. Trump was created in 1990 by a bill supported by Mr. Schumer, passed by bipartisan votes and signed into law by a Republican president, George Bush. Mr. Schumer supported getting rid of the program as part of a comprehensive immigration plan crafted by eight lawmakers and passed by the Senate in 2013. But the plan was blocked in the House by Republicans who objected to other elements they considered amnesty for illegal immigrants.
Senator Jeff Flake, a Republican from Arizona who has broken with Mr. Trump, came to Mr. Schumerâs defense on Wednesday. âActually, the Gang of 8, including @SenSchumer, did away with the Diversity Visa Program as part of broader reforms,â Mr. Flake wrote on Twitter. âI know, I was there.â
The program creates a class of immigrants called âdiversity immigrantsâ from countries with historically low rates of immigration to the United States. About 50,000 diversity visas are distributed annually, or roughly 5 percent of the total green cards issued by the United States. Nearly 14.7 million people applied last year, meaning less than 1 percent of those who seek such visas receive them.
The program has been a target of conservatives, who proposed eliminating it in legislation endorsed in August by Mr. Trump that would crack down on legal immigration. The legislation would slash legal immigration to the United States in half within a decade by sharply curtailing the ability of American citizens and legal residents to bring family members into the country.
In his remarks, Mr. Trump stressed that he wanted âmerit-basedâ immigration, suggesting that Mr. Saipov was admitted without consideration about whether he had skills that could benefit the United States. In fact, the program requires applicants to have a high school education or be employed for at least two years in jobs approved by the State Department.
Mr. Trump, who during last yearâs campaign called for a complete ban on all Muslims entering the United States, has long sought to tighten the borders. He has signed several versions of the travel ban aimed mainly at predominantly Muslim countries even as courts repeatedly intervened.
Uzbekistan was not among the countries targeted for âextreme vettingâ but Ms. Sanders said âthat may be something thatâs looked at.â
