The Democratic group Need to Impeach is airing new ads pushing four Republican senators to remove President Donald Trump from office, as public pressure campaigns surrounding impeachment ratchet up.

The ads — which are starting to air this week, as the House votes on an initial impeachment resolution — target Sens. Susan Collins of Maine, Joni Ernst of Iowa, Cory Gardner of Colorado and Martha McSally of Arizona. All four will face voters in 2020, and Need to Impeach believes that constituent pressure could push GOP senators to break ranks and vote to remove Trump in an eventual impeachment trial.


Need to Impeach is spending $3.5 million on its current ad campaign and may expand that spending.
