The Judicial Crisis Network, a top conservative political group, is spending $600,000 national airtime to boost President Trump’s Supreme Court nominee Brett Kavanaugh ahead of his confirmation vote.

The details: JCN said the 30-second ad will be aired for two weeks on CNN, MSNBC and FOX News Channel starting Thursday — the third day of Kavanaugh's confirmation hearings. JCN is a dominant outside group that helped confirmed Trump's first justice nominee, Neil Gorsuch, and it had recently launched an ad campaign to pressure vulnerable red-state Democrats to support Trump's pick.
