Pence makes clear there is no daylight between him and Trump

Hours after Mr. Trump defiantly escalated the impeachment drama by openly urging China’s government to investigate the business dealings there of former Vice President Joseph R. Biden Jr.’s son Hunter, Mr. Pence backed up his boss without apology, saying that Mr. Trump was making good on his campaign pledge to “drain the swamp.”

Mr. Pence also reiterated an earlier statement that the business Hunter Biden did in Ukraine while his father was overseeing the Obama administration’s policy toward the country was, as he put it on Thursday, “worth looking into.”

“The president made it very clear that he believes our other nations around the world should look into it as well,” Mr. Pence added.
