There are very smart lawyers who believe Donald Trump entered the White House in violation of the Constitution, which forbids the president from receiving emoluments from foreign and local governments, and that he remains in violation of it today. But the list of reasons he could be impeached keeps growing.

When Trump disclosed code-word intelligence to the Russian foreign minister and the Russian ambassador to the U.S. in the Oval Office on a lark two weeks ago, he endangered the life of an Israeli spy who had infiltrated the Islamic State.

Trump told those same Russians that firing FBI Director James Comey—whom he described as “a real nut job”—relieved “great pressure because of Russia.” Weeks earlier, he reportedly asked Comey to wind down his investigation of ousted national security adviser Michael Flynn, and when he decided to fire Comey, he told NBC’s Lester Holt, “I said to myself, I said, you know this Russia thing with Trump and Russia is a made-up story.”

Every individual item on this devastating bill of particulars eclipses the combined level of wrongdoing Republicans have sought to pin on Democratic leaders over the past decades, starting with President Bill Clinton’s sexual depravity, through the confusing miasma of Benghazi conspiracy theories under President Barack Obama, and ending with Hillary Clinton’s rule-breaking email protocols.

Each Trump scandal is well-documented, and a source of enduring national humiliation. It’s why some rank-and-file Democrats, like House representatives Maxine Waters and Al Green, are calling for his impeachment now. And yet, it is the position of nearly every leading Democrat that for both political and substantive reasons—the fear of “crying wolf,” the procedural obstacles, the lack of a completed investigation—liberals should not be calling for Trump’s impeachment.
