Franken is fair game, and his behavior is unacceptable. But as with so many of Trump’s late-night and early-morning tweets, his strategy is unclear. While it’s no surprise that he’d take a shot at Franken, his tweets call attention to his silence with regards to Moore, the embattled Alabama contender.

Over the last eight days, a series of women—first four, then five, then six, and now others—have emerged with stories about Moore. They range from the alarming, about Moore’s apparent habit of dating high-schools girls, to the distressing, like rumors he was banned from the local mall for his pursuit of the girls, to the criminal. One woman says when she was 14, Moore brought her to his house, undressed, and guided her hand to touch his genitals. Another says he offered to give her a ride home, then locked her in his car as he groped her and tried to force her head into his crotch.

Moore has offered fiery and flat denials but has not specifically rebutted most of the allegations. He told Sean Hannity that he didn’t “generally” date teenage girls but didn’t deny he had; his lawyer delivered a rambling press conference about one accuser that didn’t really refute her account at all.

As these stories mount, an increasing number of Republicans, led by Senate Majority Leader Mitch McConnell, have said they find Moore’s accusers credible and demanded that Moore drop out of the race. The National Republican Senatorial Committee and Republican National Committee have followed suit, and recent polls show Moore falling behind Democrat Doug Jones ahead of the December 12 election.

But Trump, who was in Asia when the scandal began, has remained silent. Trump supported Senator Luther Strange in the earlier GOP primary against Moore. The White House has said that if the allegations are true, Moore should step down, and left it at that. Politico reported that Republicans expected Trump to speak about the race on Wednesday, but he stayed mum instead.

Trump’s silence on Moore, and his quick reaction on Franken, stand out not just because of his party’s internal divisions over Moore. As Erin Gloria Ryan has written, declaring that all sexual harassment is unacceptable doesn’t preclude differentiating between levels of predation, and the allegations against Moore—involving teenagers, including a 14-year-old—are more serious and numerous than those against Franken. It’s true that Franken, unlike Moore, has acknowledged his inappropriate behavior; however, Franken has also apologized, unlike Moore.

More than Roy Moore, what Trump’s tweets call attention to is his own history. Not only has Trump faced accusations of sexual harassment (on various levels) from at least 16 women, but there is the matter of the infamous Access Hollywood tape from 2005, in which Trump boasted about sexually assaulting women.
