美国民主党总统候选人拜登周六呼吁众议院对特朗普和乌克兰总统泽连斯基的谈话进行调查。请看本报昨日的报道：

Allegations that U.S. President Trump courted foreign interference from Ukraine to hurt his leading Democratic rival, Joe Biden, dominated presidential politics Saturday, as Biden demanded a House investigation of Trump’s phone call with Ukraine’s leader. With Trump seizing on a familiar defense, saying Democrats were undertaking a “witch hunt” against him, Biden called on the House of Representatives to begin a new investigation of whether the president sought the interference of a foreign government to bolster his re-election campaign.

报道中的witch hunt就是“政治迫害”，过去原指对施用巫术者的迫害，现在是个常见的政治词汇，指对持不同政见者的迫害。
