周三，FBI director 在国会 说：
“with respect to former President Trump, there’s some question about whether or not it’s a bullet or shrapnel that, you know, that hit his ear”
In another exchange, Wray told Rep. Kevin Kiley (R-Calif.) either a bullet or a piece of shrapnel “is what grazed [Trump’s] ear.”

周五，FBI说：
"What struck former President Trump in the ear was a bullet, whether whole or fragmented into smaller pieces, fired from the deceased subject's rifle," the bureau said in a statement on Friday.

对周三和周五的说法，我看没有太大的差别，都是说，是子弹或者是子弹的弹片，实质是一样的。 都没有说是玻璃擦伤。周三director是提出了问题（说不确实是子弹或弹片所伤），周五的statement并没有这回答问题，只是用确定的口吻说是子弹或者子弹的弹片所伤。
针对周三的话，川普大为恼火，说
"FBI Director Christopher Wray told Congress yesterday that he wasn’t sure if I was hit by shrapnel, glass, or a bullet (the FBI never even checked!), but he was sure that Crooked Joe Biden was physically and cognitively "uneventful" - Wrong!" Trump wrote on his on social media site.
看来是川普自己加上了玻璃伤的可能性，篡改了FBI 头头的话。川普认为周五的说法更和他的意愿，认为FBI周五的说法是对自己头头在周三说法的一种道歉。
"I assume that's the best apology that we'll get from Director Wray, but it is fully accepted!" Trump wrote on Truth Social.
