Even before being elected President, Donald Trump attracted plenty of attention due to his rhetoric and actions on the campaign trail. And while most of the GOP fell into line after his 2016 win, Trump’s attacks against prominent Republicans still caused rifts between himself and small groups of Republicans.

Those rifts began to show themselves more recently following the death of longtime Republican Senator John McCain and Trump’s tariff threats against Mexico. But a group of Republicans has decided to take it a step further with a new ad campaign.

Monday’s edition of “Fox & Friends” featured ads from the group Republicans for the Rule of Law. The ad urges Congressional Republicans to take the allegations of obstruction against President Trump seriously ahead of the House Judiciary Committee’s hearing with Watergate witness John Dean. The hearing with Dean is meant to discuss evidence of possible obstruction Robert Mueller’s investigation may have uncovered and its validity.

The ad uses clips of the Watergate hearings Dean was involved in here Republican members of the House Judiciary Committee raised similar concerns regarding then-President Richard Nixon.

“Congressional Republicans are more than happy to admit in private that they are troubled, disappointed, and disturbed by President Trump’s abuses of executive power,” Republicans for the Rule of Law spokesperson Chris Truax said. “When none of their constituents can hear them, they speak frankly about their moral qualms and objections about their roles in undermining the original design of our Constitution. Their constituents — and all Americans — deserve to hear the same in public.”

Currently, Michigan Rep. Justin Amash is the only serving Republican in Congress who has thrown his support behind starting impeachment proceedings because of the obstruction claims. He also supports Truax’s statement, saying other Republicans in Congress have expressed concern over Trump behind closed doors.

And this is just the latest in a series of ads the Republicans for the Rule of Law have aired. Previous ones had shown Republican-appointed prosecutors saying Trump would have been charged with obstruction if he wasn’t President.
