【白宫官员：取消对加拿大征收50%的钢铁、铝关税】金十数据3月12日讯，美国白宫贸易顾问纳瓦罗当地时间周二下午表示，特朗普总统周三将不会把加拿大钢铁和铝进口关税提高到50%。六个小时前，特朗普宣布计划将加拿大金属25%的进口关税提高一倍，以回应加拿大安大略省对美出口电力征收25%附加费（在特朗普发出威胁后已取消）的决定，而安大略省的这一举动本身就是对特朗普对加拿大进口商品征收25%关税的报复。纳瓦罗还表示，对所有进口的钢铁和铝的25%关税将于12日午夜开始实施，且不会有豁免

Since the violent storming of Capitol Hill and subsequent ban of former U.S. President Donald Trump from Facebook and Twitter, the removal of Parler from Amazon’s servers, and the de-platforming of incendiary right-wing content, messaging services Telegram and Signal have seen a deluge of new users. In January alone, Telegram reported 90 million new accounts. Its founder, Pavel Durov, described this as “the largest digital migration in human history.” Signal reportedly doubled its user base to 40 million people and became the most downloaded app in 70 countries. The two services rely on encryption to protect the privacy of user communication, which has made them popular with protesters seeking to conceal their identities against repressive governments in places like Belarus, Hong Kong, and Iran. But the same encryption technology has also made them a favored communication tool for criminals and terrorist groups, including al Qaeda and the Islamic State.
Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.
