Ted Cruz Rafael (Ted) Edward CruzSenate GOP set to vote on Trump's Supreme Court pick before election Supreme Court fight pushes Senate toward brink Crenshaw looms large as Democrats look to flip Texas House seat MORE (R-Texas) on Wednesday blamed Democratic politicians for "encouraging" over-the-top political behavior and rhetoric, hours after authorities intercepted a series of suspicious packages sent to prominent Democrats and CNN earlier in the day.

Cruz said on MSNBC's "Meet the Press Daily" that all sides should tone down their rhetoric and disagree in a civil manner.

"I think the media always focuses on on the president," Cruz said. "There are too many Democratic politicians that are actively encouraging this."

The Texas senator then cited comments from Rep. Maxine Waters Maxine Moore WatersPowell, Mnuchin stress limits of current emergency lending programs Pelosi: House will stay in session until agreement is reached on coronavirus relief Omar invokes father's death from coronavirus in reaction to Woodward book MORE (D-Calif.), who in June urged supporters to confront Trump administration officials in public spaces.

Cruz singled out Waters hours after Capitol Police intercepted a suspicious package at a congressional mail-sorting facility addressed to her.

Booker's office has argued that right-wing outlets and conservative politicians have taken his remarks out of context.

Cruz added that both major parties need to do a better job of discouraging hostilities before quickly pivoting his attention to another prominent Democrat, former presidential candidate, Hillary Clinton Hillary Diane Rodham ClintonThe Memo: Trump furor stokes fears of unrest Bloomberg rolls out M ad buy to boost Biden in Florida Hillicon Valley: Productivity, fatigue, cybersecurity emerge as top concerns amid pandemic | Facebook critics launch alternative oversight board | Google to temporarily bar election ads after polls close MORE.

"I thought it was unfortunate when Hillary Clinton said 'we can be civil after the Democrats win. That's wrong," Cruz said, referencing comments from Clinton earlier this month.

The U.S. Secret Service said it intercepted a package earlier Wednesday addressed to Bill and Hillary Clinton's New York home.

Cruz condemned the threats, asserting that citizens should be able to disagree on substance without resorting to violence.

"This has been a very divided time, a polarized time," he said. "Violence is never okay, and it doesn't matter where on the political spectrum it comes. These bombs that were apparently sent to Soros and Obama and Clinton, is deeply troubling. On its face it appears to be a terrorist act. I hope the person is caught, is prosecuted and goes to jail for a long, long time."

Numerous Republicans and Democrats have called for an easing of political hostilities after Wednesday's bomb threats, while simultaneously blaming the other side for inflaming tensions.

Democratic leaders pointed to Trump's attacks of Democrats at campaign rallies and elsewhere, where he has labeled the Democratic Party an "angry mob," and attacked news outlets as the "enemy of the people."

Republicans have, in recent months, seized on protests from liberal activists, some of whom have confronted lawmakers in public, as a sign of deteriorating political discourse.
