GOP Sen. Lindsey Graham says Trump canceling Pelosi's overseas trip was 'sophomoric' and 'inappropriate'

President Trump's cancellation of House Speaker Nancy Pelosi's (D-Calif.) overseas trip, seemingly in response to her request to delay the State of the Union, is already receiving pushback from one of his biggest supporters in Congress.

Sen. Lindsey Graham (R-S.C.) tweeted that "one sophomoric response does not deserve another" in reaction to Trump's letter. While he said the House speaker's "threat" to cancel Trump's State of the Union address was "very irresponsible and blatantly political," Trump striking back by denying her the use of military aircraft for a previously undisclosed trip was also "inappropriate."

One sophomoric response does not deserve another. Speaker Pelosi’s threat to cancel the State of the Union is very irresponsible and blatantly political.

President Trump denying Speaker Pelosi military travel to visit our troops in Afghanistan, our allies in Egypt and NATO is also inappropriate.

I am glad the Speaker wants to meet our troops and hear from our commanders and allies. I am very disappointed she’s playing politics with the State of the Union.

I wish our political leadership could find the same desire to work for common goals as those who serve our nation in uniform and other capacities.

Pelosi had mentioned the ongoing government shutdown as the reason for potentially canceling the State of the Union, and Trump, in turn, cited the shutdown as the reason for canceling her trip. Graham says he has been attempting to find a bipartisan agreement to end the impasse in Congress but has had no luck, saying last week after Trump reportedly rejected a plan he was involved with that he has "never been more depressed."
