Fox News contributor Katie Pavlich expressed skepticism about Rep. Adam Schiff (D-Calif.) urging his Republican colleagues to speak out against President Trump.

In an open letter published in The Washington Post, Schiff, who is chairman of the House Intelligence Committee, suggested Republicans share any misgivings they have about Trump's national emergency declaration, which Schiff called "a plainly unconstitutional abuse of power."

The letter reads, in part:

When the president attacked the independence of the Justice Department by intervening in a case in which he is implicated, you did not speak out. When he attacked the press as the enemy of the people, you again were silent. When he targeted the judiciary, labeling judges and decisions he didn’t like as illegitimate, we heard not a word. And now he comes for Congress, the first branch of government, seeking to strip it of its greatest power, that of the purse.

Many of you have acknowledged your deep misgivings about the president in quiet conversations over the past two years. You have bemoaned his lack of decency, character and integrity. You have deplored his fundamental inability to tell the truth. But for reasons that are all too easy to comprehend, you have chosen to keep your misgivings and your rising alarm private.

That must end. The time for silent disagreement is over. You must speak out.

On "Outnumbered" Friday, Pavlich noted that some Republican lawmakers already have publicly spoken out against Trump declaring a national emergency to secure border wall funding.

Brian Brenberg agreed that Schiff was "factually incorrect" to suggest that Republican lawmakers have not publicly disagreed with Trump on various issues throughout his presidency.

"But for Adam Schiff to think that Republicans on Capitol Hill are going to be allies with him after everything that he's done and plans to do, I think that he's hoping for a little too much," Pavlich said.
