[請益] as的用法

[bruce0428 (bruce)]

Trump complained in tweets that he wasn't getting enough credit for his
meeting with Kim and railed that "Much of our news media is indeed the enemy
of the people" as he headed to sit down with Putin.

這裡的as是關係代名詞,
Much of our news media is indeed the enemy
of the people的先行詞

還是做為  "因為"解釋


如果是關代
那這句的意思怎麼說比較順呢
