Host Jake Tapper circled back to the subject, but Cramer’s answers remained basically the same.

Rep. Lee Zeldin (R-N.Y.) also dodged the question during an appearance on ABC. Sens. Cory Gardner (R-Colo.) and Joni Ernst (R-Iowa) made headlines last week for repeatedly refusing to answer similar questions.

Sen. Ted Cruz (R-Texas) responded "of course not" when asked by CBS' Margaret Brennan whether it was appropriate for Trump to ask China to investigate Biden's family.

"Elections in the U.S. should be decided by Americans and it's not the business of foreign countries, any foreign countries, to be interfering in our elections," Cruz added, without mentioning Trump by name.

Republicans have generally been reluctant to answer questions about whether it is proper for Trump to solicit foreign assistance, instead attacking House Democrats over how they’re conducting the investigation.

“There should be a process, but instead what Adam Schiff wants is to get United States of America drunk on his favorite cocktail,” Zeldin said Sunday on ABC’s “This Week.“ “There's three ingredients: One is cherry-picking leaks, second is withholding facts, and three is just outright lying.”

Republicans also have been pressuring Speaker Nancy Pelosi to hold a vote on an impeachment inquiry on the House floor, citing precedent in past presidential impeachments. But Pelosi has refused, saying there’s no constitutional or legal requirement to do so.

Rep. Jim Himes (D-Conn.), a member of the House Intelligence Committee, said Sunday he’s fine with holding an inquiry vote but doesn’t believe it’s necessary.

“This idea that the process is somehow not — is not — fair is just a fiction designed to avoid the question of whether the conduct of the president is good or not,” Himes said on ABC.

Republicans have had equal access to witnesses during closed-door depositions, Himes argued, comparing the inquiry to a grand jury investigation.

“Impeachment is more akin to a grand jury indictment, and in a grand jury indictment, it happens behind closed doors, there aren’t cross-examinations, evidence is presented,” Himes said. “if there is a trial in the Senate, [Republicans] will be afforded all of the other due process that they have and will always be entitled to.”

Lawmakers return to the Capitol on Tuesday after a two-week break that saw a flurry of activity on the House side as investigators heard closed-door testimony from multiple current and former administration officials involved in the Ukraine controversy.

Marie Yovanovitch, a former U.S. ambassador to Ukraine, testified Friday that she was abruptly forced out of her role earlier this year after a “concerted campaign” by people “with clearly questionable motives.” Yovanovitch’s testimony was remarkable because it came in defiance of a State Department directive to block House impeachment investigators’ access to administration officials and documents related to the probe.

Yovanovitch instead agreed to comply with a House subpoena to attend. Similarly, lawmakers are set to hear much anticipated testimony from Gordon Sondland, the U.S. ambassador to the European Union, on Thursday. Sondland was subpoenaed after he didn't show up for a scheduled deposition earlier this week at the direction of the State Department.

Democrats are eager to hear directly from Sondland about his role in pressuring Ukrainian officials to investigate Biden and his son in exchange for $400 million in U.S. military aid and a White House meeting between Trump and Zelensky.

In a cache of damning text messages released last week by Kurt Volker, Trump’s former special envoy to Ukraine, Sondland told the other officials involved that “potus really wants the deliverable.”

In a later text exchange, in which another official wrote it's “crazy” to withhold U.S. military aid as part of a pressure campaign to help damage Trump’s political rival, Sondland responds hours later insisting that there are “no quid pro quo’s of any kind.”

Republicans have repeatedly pointed to Sondland’s response in an effort to defend the president, saying without a quid pro quo, there isn’t any proof that Trump or his allies committed a crime. The White House earlier this week announced a full blockade of Democrats’ impeachment inquiry, calling it an “illegitimate” effort. But Sondland, like Yovanovitch, is expected to defy the administration’s directive.

Sondland plans to tell House investigators later this week that his text response came at the direction of the president, after a telephone conversation with Trump, and he doesn’t know whether the president was telling the truth, according to a report in The Washington Post.

Lawmakers are also expecting to hear testimony from Fiona Hill, Trump’s former top adviser on Russia, on Monday.

And Democrats have set several deadlines this week for the administration to hand over documents related to the probe — including from Vice President Mike Pence, the Pentagon, the Office of Management and Budget and Rudy Giuliani, Trump’s personal lawyer and a key figure in the probe — although they aren’t expecting much.

Defense Secretary Mark Esper said Sunday on CBS that his department will "do everything we can to comply" with Democrats' subpoena.

Pelosi and other top Democrats have refused to put a firm timeline on the inquiry, only saying they want to move “expeditiously.” But privately, Democrats say they hope to wrap up their investigation — including a potential House vote on articles of impeachment — by the end of the year.

“The whole point of this inquiry is to save the Constitution of the United States,” Pelosi told Democrats on a private call Friday afternoon. “I’ve said before: Trump, himself, is not worthy of impeachment because it’s divisive in the county. But our Constitution is worth it.”
