Top leaders in Congress won't appear with Trump in Pittsburgh Ryan, McConnell turn down White House invitation due to scheduling conflicts.

Several top congressional leaders from both parties passed on an invitation from the White House to join President Donald Trump on his visit to Pittsburgh on Tuesday in the wake of the shooting at the Tree of Life synagogue, according to several sources familiar with the matter.

With the midterm elections just one week away, Senate Majority Leader Mitch McConnell and House Speaker Paul Ryan are unable to make the trip because of scheduling conflicts.

Senate Minority Leader Chuck Schumer and House Minority Leader Nancy Pelosi declined the invitation, according to aides to both Democrats.

The White House has not responded to ABC News' request for comment.

Also not expected to appearwith Trump despite being invited: Republican Sen. Pat Toomey of Pennsylvania.

"Senator Toomey attended a vigil, met with law enforcement, and leaders of Pittsburgh's Jewish community this past weekend and yesterday. Today, Senator Toomey will be attending to prescheduled commitments in southeast Pennsylvania," Toomey's spokesman Steve Kelly told ABC News.

Eleven worshippers, including a 97-year-old woman, were gunned down inside the Tree of Life synagogue in Pittsburgh's Squirrel Hill neighborhood Saturday morning.

Both Ryan's and McConnell's press teams dismissed the characterization that they outright declined the invitation to appear alongside Trump.

"He was unable to attend due to long-planned events in Kentucky. He did, however, speak to the shootings at two different events yesterday," a spokesman for McConnell told ABC News. "He did not “decline” or “turn down” the invitation."
