NBC晚间新闻 五角大楼收到可疑信件

（单词翻译）

 Initial field tests on two suspicious-looking envelopes addressed to the Pentagon suggested possible traces of the deadly poison known as ricin. They were stopped at a mail sorting facility separate from the Pentagon building addressed to Defense² Secretary James Madison and the Chief of Naval³ Operations John Richardson.

A similar letter was addressed to the White House but stopped well before it got there. Another was sent to the Houston campaign office of Senator Ted¹ Cruz but tests there for anything hazardous⁴ turned up negative. Law enforcement officials say tonight they don't consider any of these letters to be dangerous and they say they are following some promising⁵ leads about where the letters may have come from.

工作人员对寄往五角大楼的两个可疑信封进行了初步现场测试，测试表明，信上可能有蓖麻毒素的痕迹。这两封信在五角大楼外的一个邮件分拣处被拦截，这两封信分别写给国防部长詹姆斯·麦迪逊和海军作战部长约翰·理查森。一封类似的信被寄往白宫，但在它到达白宫之前就被拦截了。另一封信被寄往参议员特德克鲁兹(Ted Cruz)在休斯顿的竞选办公室，但那里进行的有害物质测试结果都是阴性的。执法官员今晚表示，他们认为这些信件中没有一封是危险的，并表示正在循着一些可疑的线索，了解这些信件可能来自哪里。
