For reporting the news heard on TV, it can be as follows:<br/><br/>1. I <b>hear</b> the prime minister is going to resign.<br/><br/>2. I <b>have heard</b> the prime minsiter is going to resign. (the present perfect tense seems logic to me because I heard the news before I report it)<br/><br/>But for the 1st sentence, I don't know why the simple present tense is also acceptable in this contest.<br/><br/>Could you explain the reason to me?<br/><br/>Thank you
