对…的暗杀企图唐纳德·特朗普周末在宾夕法尼亚州的竞选集会上，这位前总统在全国范围内引起了轩然大波，并被列入了枪支暴力的美国领导人名单。
这周六拍摄一名观众和嫌疑枪手死亡，另外两人受伤，特朗普右上耳朵枪伤出血。
在袭击发生后的几天里，许多人都想知道这一令人痛心的事件将如何影响选举季的剩余时间——历史书可能会提供这个问题的洞察力。
对特朗普的攻击立即引起了人们对1981年试图暗杀时任总统罗纳德·里根的比较。
1981年3月30日，当里根在美国劳工联合会和工业组织大会成员面前发表演讲后离开大楼时，华盛顿特区希尔顿酒店外爆发了枪声。
枪手小约翰·欣克利(John Hinckley Jr .)用一把点22口径的左轮手枪向总统开了六枪，总统举起手向人群挥手。子弹击中了里根的胸腔，离他的心脏只有几英寸，刺穿了他的肺。
另外三个人也在袭击中中弹，包括里根的新闻秘书詹姆斯·布雷迪，他因头部中弹而致残。
随着枪声响起，当时70岁的总统立即被特勤局特工包围，并被推进一辆等候的豪华轿车，迅速送往乔治华盛顿大学医院进行救命的紧急手术。
里根和特朗普在袭击期间被特勤局特工包围，两人在事件发生时都举起了手(里根在前面，特朗普在后面挥舞着拳头)，这两者之间惊人的视觉相似之处是显而易见的。
两位总统还试图在枪击事件后展示勇气和韧性的形象。里根尽管身负重伤，却选择走进医院;特朗普选择在袭击发生仅两天后，在共和党全国代表大会上按计划露面并发表讲话。
这两次攻击的另一个相似之处是围绕的审查特勤局。据美联社报道，小欣克利之所以能够在里根离开酒店时向他开枪，是因为他将自己置身于一群记者和观众之中，而这些人事先没有经过安全检查美联社.
两名执法官员告诉ABC新闻，在宾夕法尼亚州巴特勒的集会上，嫌疑枪手托马斯·克鲁克斯爬上屋顶并开枪的大楼是当地警察战术小组监视人群的集结地。
消息人士此前告诉ABC新闻，该建筑已被清扫，但调查人员正试图确定屋顶通道是否已被正确锁定。
虽然自1981年以来，政治格局已经发生了变化，但只有时间才能证明对特朗普的攻击是否会获得里根的持久钦佩和公众认可，根据一份盖洛普民意测验.
此外，里根的“让美国再次伟大”竞选口号是特朗普在2020年大选中以及在2024年整个选举周期中广为人知的选择，这是团结两位共和党领导人的另一条政治纽带。
根据国会研究服务处针对总统和候选人的直接暗杀企图至少发生过15次。
被暗杀的四位美国总统是亚伯拉罕·林肯、詹姆斯·a·加菲尔德、威廉·麦金利和约翰·肯尼迪。
How Trump's assassination attempt compares to the attempt on Ronald Reagan's life in 1981
The assassination attempt made againstDonald Trumpduring his campaign rally in Pennsylvania over the weekend sent shockwaves through the nation and added the former president to a list of American leaders who have been targeted by gun violence.
Theshooting Saturdayleft one spectator and the suspected gunman dead, two others injured and Trump bleeding from a gunshot wound to his upper right ear.
In the days following the attack, many have been left to wonder how the harrowing event will impact the remainder of the election season -- a question history books may offer insight into.
The attack on Trump garnered immediate comparisons to the attempt on the life of then-President Ronald Reagan in 1981.
On March 30, 1981, gunfire erupted outside the Hilton Hotel in Washington, D.C., as Reagan was exiting the building after delivering a speech before members of the American Federation of Labor and Congress of Industrial Organizations.
The shooter, John Hinckley Jr., fired six rounds from a .22-caliber revolver at the president, who had his hand raised, waving to the crowd. The bullet hit Reagan's ribcage, just inches from his heart, and punctured his lung.
Three other individuals were also shot in the attack, including Reagan's press secretary, James Brady, who was disabled from the gunshot striking his head.
As shots rang out, the then-70-year-old president was immediately swarmed by Secret Service agents and pushed into a waiting limousine that rushed him to George Washington University Hospital for life-saving emergency surgery.
The striking visual similarities between Reagan and Trump being swarmed by Secret Service agents during the attack and both men having a raised hand at the time of the incident (Reagan before and Trump with his fist in the air after) -- are noticeable.
Both presidents also sought to display an image of courage and resilience in the aftermath of the shootings. Reagan chose to walk into the hospital despite being seriously wounded; Trump opted to make his scheduled appearance and speech at the Republican National Convention only two days after the attack.
Another resemblance between the two attacks is thescrutiny surroundingthe Secret Service. Hinckley Jr. was able to shoot at Reagan as he was exiting the hotel because he positioned himself among a crowd of journalists and spectators who were not screened by security ahead of time, according to theAssociated Press.
At the rally in Butler, Pennsylvania, the building where suspected gunman Thomas Crooks scrambled onto the roof and opened fire was the staging area for the local police tactical team watching the crowd, two law enforcement officials told ABC News.
Sources previously told ABC News that the building had been swept, but investigators are trying to determine whether roof access had been properly locked down.
While the political landscape has changed since 1981, only time will tell if the attack on Trump will garner the lasting admiration and public approval felt by Reagan, whose already high approval rating only increased after the shooting, according to aGallup poll.
Additionally, Reagan's "Make America Great Again" campaign slogan, famously co-opted by Trump in the 2020 election and throughout the 2024 election cycle, is another political tie that unites the two Republican leaders.
According to theCongressional Research Service, direct assassination attempts against presidents and candidates have occurred on at least 15 separate occasions.
The four U.S. presidents who were assassinated were Abraham Lincoln, James A. Garfield, William McKinley and John F. Kennedy.
